Pfizer and Moderna COVID vaccines are highly effective against coronavirus variants.

Coronavirus Variants study from Qatar

“I think B.1.351 variant is the worst of all know till date,” says Laith Jamal Abu Raddad, an infectious-disease epidemiologist at Weill Cornell Medicine in Doha, Qatar. He added that we had the tools to tackle these variants.

Research from Qatar study compared SARSCOV2 rates in vaccinated and unvaccinated people. Those who received two shots were 90% less likely to develop an infection. The researchers hard find any severe cases of CVOID-19 by both B.1.135 and B.1.1.7 among fully vaccinated individuals.

Coronavirus Variant B.1.351

Results from Moderna’s effect suggested that booster shot of the updated vaccine give a strong response against B.1.351.

Shabir Madhi, a vaccinologist from South Africa, says the Qatari results are compelling.  Madhi said if we protect high-risk individuals, we could return to a normal lifestyle.

Research at the NYU Grossman School of Medicine and NYU Langone Center found that antibodies produced in response to the vaccine are a little weaker against the variants. He added further that some antibodies may not work against variants, but you still have a lot of antibodies that should work against the variants.
