Vaccines and viruses in the war epic.

Text . . . The king of the northwest does not leave the world small, such as a village.
wherever the study of viral diseases is lost, it will be all mankind (Joshua Lederberg, winner of the 1958 Nobel Prize in Physiology or Medicine).
Since the beginning of 2020, the new coronavirus infection has swept the globe, with more than 10 million cases diagnosed worldwide.
the World Health Organization's director-general, Mr Tan Desai, said there were 136,000 new cases in one day on June 7 alone.
the war between man and virus, whether it is a foot high or a foot high.
1 virus's harm to humanity Occurred in an international conflict in 1914 that involved most of Europe, as well as Russia, the United States, the Middle East and other regions, known as World War I.
November 11, 1918, when the 52-month-old First World War ended and the war ended in the defeat of the Allies, with some 65 million people fighting, 10 million killed and 20 million injured.
more tragic than the war casualties were the "Spanish influenza" outbreak caused by the H1N1 influenza virus near the end of World War I, which swept across the Americas, Europe, Asia and even Eskimo clusters, infecting more than 500 million people worldwide and killing 50-100 million, far more than the death toll from World War I.
According to the United Nations news network, the World Health Organization Director-General Tan Desai said at an online press conference in Geneva on June 1, 2020, the Government of the Democratic Republic of the Congo (DRC) today (1) announced that a new outbreak of the Ebola virus near the city of Mbandaka in the north-western province of Equateur.
preliminary information provided by the Ministry of Health in the Democratic Republic of the Congo, six ebola cases have been detected so far, four of whom have died.
more people may be diagnosed as monitoring activity increases.
this is the 11th outbreak in the Democratic Republic of the Congo since the Ebola virus was first detected in 1976.
and the Ebola outbreak that ravaged West Africa in 2014 killed more than 6,000 people.
early 2020, the new coronavirus infection has swept the world, and by June 29, 2020, a total of 10.13 million people have been confirmed worldwide (except China) and 500,000 deaths have been confirmed; 640,000, the cumulative death toll of 130,000; China is the first country to prevent and control the epidemic, the cumulative number of confirmed cases now reached 85,000, the existing number of more than 511 confirmed, of which about 318 people are after June 11, Beijing again a small outbreak of confirmed cases.
outbreak is a war without smoke, which has brought great impact to our economic, social and spiritual life.
Figure 1 Global, U.S. and China outbreaks, as of 2020.6.29, screenshots from the Origin and Development vaccine of phoenix network 2 vaccine is a milestone in the history of human medicine, the main means of human control of infectious diseases, is regarded as one of the greatest public health achievements of the 20th century.
as early as the Tang and Song periods, China has been using "vaccines" to prevent smallpox.
at that time, there are pox clothing method, pox slurry method, dry seedling method, water seedling method 4 kinds: (1) pox clothing method: to children wear inglions carrying smallpox virus; Inside the nostrils of the subject scored; (3) The dry seedling method: blowing powdered dry skin into the nostrils of the inoculated subject; (4) Water seedling method: wrapping the pox powder with pox slurry, pinching into a nucleosome, stuffed into the nostrils.
these methods are gradually introduced to Western countries through India and West Asia.
in 18th century Britain to vaccinate against smallpox with bovine pox, the cattle pox vaccine ended the threat to humans for hundreds of years of smallpox virus, after which the vaccine became an immune method into the human medicine.
from the end of the 19th century to the beginning of the 20th century, The French scientist Pasteur invented the technology of detoxifying live vaccines, the development of rabies vaccine, cacao seedlings and other products still used to date.
the middle of the 20th century, polyglycemic protein binding vaccine, proteomic vaccine, subunit vaccine, etc. has become one of the important achievements in the history of vaccine development.
1970s, the development of molecular biology has enabled humans to manipulate genes at the molecular level, and gene recombinant vaccine technology has been invented.
the 21st century, with the development of genomics, humans began to develop genome-based vaccine strategies.
Figure 2 Vaccine Origin and Development Timeline 3 Vaccine is an effective means of combating multiple viral infections1. The naturally infectious albethavirus has completely disappeared" smallpox is always in the dark, filling the cemetery with corpses.
tortureits its captives with endless fear, causing the living to spread its prestige.
it turns the baby into a monster that makes the mother shudder, and makes the eyes and faces of the girl sourcing as a nightmare for lovers.
" - T.B. Macaulay's British History, 1980, the World Health Assembly determined that smallpox had been wiped out worldwide.
it was the successful development of the vaccine that allowed the virus, which has been threatening humanity for centuries, to completely disappear (except for retained samples stored at the U.S. Centers for Disease Control and the Russian National Center for Virology and Biotechnology).
the end of the 18th century, the smallpox outbreak caused by the smallpox virus caused global panic, killing hundreds of thousands of people each year.
this is an ancient disease dating back at least to the third century BC.
infected people, regardless of wealth, rich and poor, regardless of men, women and children.
has a fatality rate of about 30% for heavy-duty smallpox, but is immunized for life after recovery.
smallpox virus belongs to the pox virus department, is a large (200 to 400 nm) DNA virus, strong resistance, rapid reproduction, can survive from a few months to a year and a half.
research report shows that the smallpox virus initially originated in livestock, and then, with the development of livestock, in the extremely dirty environment, pox virus gradually evolved into smallpox virus, so that unsuspecting human losses.
and in the centuries that followed, the smallpox virus was suppressed and a major infection occurred every few decades.
it wasn't until July 2018 that the FDA approved the first drug to treat smallpox--- p37 protein small molecule inhibitor, and the preveloma.
vaccination remains the only preventive tool available to us, and smallpox is the only viral infection that has been eliminated by humans to date.
2. A 99 per cent reduction in poliovirus estrain is a poliovirus that causes poliomyelitis, a widespread spread and an acute infectious disease.
virus often invades the central nervous system, damages the front corner of the spinal cord motor nerve cells, leading to limb relaxation paralysis, but also because it is commonly found in children, so commonly known as polio.
Figure 3 Poliovirus, derived from Reference 7 poliovirus infection, rapid transmission, when the living environment is crowded and poor sanitation conditions, the virus can be the body without specific antibodies of all family members infected.
in vulnerable, warm and humid areas, fecal-mouth transmission, viral contamination of household goods, drinking water contamination, etc. can all contribute to polio outbreaks.
, therefore, the timely use of polio vaccine for prevention is extremely important.
poliovirus is divided into type I, II and III according to its antigen immunogen, which is the key infectious disease of WHO's program immunity control.
1988, who set a global target for polio eradication by the year 2000.
2000, our country has been recognized as polio-free by the WHO.
globally, while the goal of eradicating the virus has not been achieved, the incidence of polio has declined significantly.
WHO recommends that countries replace OPV (oral poliovirus vaccine, oral poliovirus vaccine, OPV) with IPV (inactivated poliovirus vaccine, inactivated poliovirus vaccine), iPV is better ate and safer than OPV.
2019, China has changed the polio vaccination program from 1 dose of IPV-3 dose bOPV to 2 doses of IPV-2 dose bOPV.
OPV is a vaccine containing i type, type II, type III of any serotype vaccine, bOPV is a vaccine containing any two serotypes, tOPV is a trivalent vaccine containing all serotypes, with the elimination of type II poliovirus, now generally OPV is a vaccine containing Type I serotype, for sugar pills, bOPV is i-type i-type, III serotype of divalent vaccine.
person is the natural host of poliovirus, and so far there is no specific treatment for poliovirus infection.
before the advent of the vaccine, poliovirus was one of the main causes of permanent disability;
3. Early on the first HPV vaccine to prevent cancer, awareness of the human papillomavirus (HUMAN papillomavirus, HPVs) was limited, and the disease simply known as benign self-limiting diseases such as skin and genital warts, but based on epidemiological data on cervical cancer in the late-stage system, cervical cancer was found to be highly associated with HPV infection.
Figure 4 Human papillomavirus DNA and shell protein, pictured from Reference 8 cervical cancer is the most common gynecological malignant tumor, data from the world show that the mortality rate of the disease is very high.
in recent years, the widespread use of cervical cytology screening and the vaccination of HPV vaccine have enabled early detection and reduction of cervical cancer and precancerous lesions.
the WHO earlier proposed the "Global Elimination of Cervical Cancer by 2030" target, the coverage of HPV vaccination for girls under 15 years of age should reach more than 90%.
more than 100 countries around the world have added the HPV vaccine against cervical cancer to routine immunization programmes and state-funded vaccination services, and even Rwanda, an African country with poor sanitation and poor medical conditions, is determined to be "the first country in the world without cervical cancer" to make HPV vaccine available to women across the country amid questions around the world.
many countries are currently providing HPV vaccination against HPV-infected cervical cancer and other related cancers.
the INTRODUCTION of the HPV vaccine in 2006 and the same year that Austria launched the HPV vaccination programme; in 2008, the UK and its local authorities launched a school vaccination programme for girls aged 12-13, as well as a three-year catch-up programme for girls under 18 years of age; and in the same year, Scotland launched a national HPV vaccination programme, which provides for girls under 18 years of age.
Scotland also conducted an eight-year study of the HPV vaccination programme for women, which found that the routine vaccination rate in Scotland was about 90 per cent and that the catch-up part of the programme was about 65 per cent, leading to a significant drop in high-risk HPV infections in Scotland in recent years.
we can confirm that vaccination programmes have begun to profoundly change the prevalence of HPV 16 and HPV 18 among Scottish women.
In 2019, following the 2008 UK vaccination programme, the UK government announced that it would extend the vaccination programme to boys from September, while in parts of Canada, HPV vaccines are being introduced to uninfected women as part of a cervical screening process, which could protect older women from cervical cancer, a process that could be adopted by the international community, including the UK.
since April 10, 2018, Shenzhen has included HPV vaccines, including the tetravalent HPV vaccine and the divalent HPV vaccine.
from the actions of countries around the world, people are also preparing to use the HPV vaccine to gradually eliminate the HPV virus, reduce the incidence of cervical cancer and related cancers.
4. The use of hepatitis B vaccine significantly reduces the rate of hepatitis B infection currently known to be a type A, B, C, D-type and type D virus.
hepatitis B virus (HBV) is the pathogen that causes hepatitis B (hepatitis B) and is a DNA virus, one of the most important factors contributing to the global burden of hepatitis disease.
Figure 5 HBV infection cells, pictured from Reference 9 after years of medical development, epidemiological studies have shown a link between HBV infection and chronic liver disease, including liver cancer and cirrhosis.
HBV infection is a global public health problem, and given the high incidence and mortality of hepatitis B worldwide, the world is committed to controlling its spread and morbidity through immunization programmes.
at present, with the production and input of genetically engineered vaccines, the prevalence of hepatitis B vaccine has increased year by year, and the infection rate is on a downward trend.
1992, the World Health Organization (WHO) recommended that babies be vaccinated against hepatitis B within 24 hours of birth.
the same year, China's hepatitis B vaccine into the children's immunization management, in 2005 the hepatitis B vaccine into the children's immunization program, the implementation of free vaccination.
2013, WHO statistics show that 181 countries have included hepatitis B vaccine in their immunization program, and 107 countries require the vaccination of newborns within 24 hours of birth.
According to the World Health Statistics 2018 published by the WHO, the global use of hepatitis B vaccine has significantly reduced the prevalence rate of chronic hepatitis B virus, with the prevalence rate of hepatitis B in children under 5 years of age in the pre-vaccine era dropping to 1.3% in 2015, and the prevalence of hepatitis B in the general population has decreased from 4.3% to 3.5%.
5. Vaccine prevention of influenza influenza is becoming more popular influenza (influenza) and the common influenza, is caused by influenza virus influenza, mainly through droplets spread through the eyes, mouth, nasal cavity, viral pollutants and other direct.
