The recent surge in beta variants: How effective is the Covid vaccine against beta variants?

The beta variant of the coronavirus was first discovered in South Africa and is believed to be the main cause of the second wave of viruses in South Africa

What is a beta variant?

The beta variant, also known as B.

It is believed that this strain is not more deadly than any other mutation.

Early research results indicate that the antibodies produced by those using Pfizer vaccines are not very effective against the strain

However, later studies on data from 800 people in South Africa showed that this vaccine is 100% effective in preventing symptomatic COVID-19

Pfizer has announced that it is developing an enhanced vaccine specifically targeting new variants

AstraZeneca

Research on whether the AstraZeneca vaccine is effective for this strain is much smaller

A small study of 2,000 people in South Africa showed that the AstraZeneca vaccine has the least protection against new strains

In March, a research report showed that the efficacy of two doses of AstraZeneca vaccine against mild to moderate infections was only 10.

The trial was conducted from June 24 to November 9, and the company said: AstraZeneca is discussing a future version of our COVID-19 vaccine with the British government to specifically address the variant problem

We will share more details in due course

Moderna

The effectiveness of the Moderna vaccine against beta strains still needs to be tested

However, a study conducted in the United States found that this vaccine proved effective against beta variants of primates

The researchers wrote: "These data highlight the importance of optimizing the main and enhancement protocols for neutralizing antibody responses, especially for B.
