6 Yue 3 Ri , LANCET published the Pfizer vaccine ( BNT162b2South Africa mutants (B.
The results of the study showed that Pfizer vaccines had lower levels of antibodies against the Indian variants , and over time, the levels of antibodies gradually decreased.
In this study , the researchers analyzed 250 received one or two doses of Pfizer -BioNTech COVID-19 antibody vaccine healthy human blood , they used a highly accurate high-throughput virus neutralization assay , were tested "in The ability to prevent the original new coronavirus strain , D614G , B.
In this study , the researchers analyzed 250 received one or two doses of Pfizer -BioNTech COVID-19 antibody vaccine healthy human blood , they used a highly accurate high-throughput virus neutralization assay , were tested "in The ability to prevent the original new coronavirus strain , D614G , B.
The results of the study found that after a single dose of Pfizer-BioNTech, 79% of people had a quantifiable neutralizing antibody response to the original strain, but B.
In people who received two doses of Pfizer-BioNTech vaccine, compared with the original strain, the level of neutralizing antibodies against the B.
It is worth noting that in all variants, the increase in age was significantly correlated with the decrease in antibody levels , but no association of gender or body mass index with the decrease in antibody levels was observed .

Further , the second dose Pfizer vaccineafter , antibody levels over time decreased .
Further , the second dose Pfizer vaccineafter , antibody levels over time decreased .
In summary , the results suggest that the current crown for the new variant is the best way to quickly provide a second dose, and for those on these new variants of immune provide human enhancer may not be high.
