Covid-19 Update: Once again there is an increase in the cases of corona virus worldwide, the reason behind which is the variants associated with them. Now how effective the vaccine is on these variants, it is being ascertained.
Pfizer and J&J’s vaccines are effective on Delta variants (Vaccine Efficacy on Delta Variant) – symbolic picture
Covid Vaccines For Variants: After getting new variants of corona virus, many types of studies are being done around the world. In which efforts are being made to find out, how effective are the vaccines on these variants. The anti-COVID-19 vaccine of American companies Pfizer (Pfizer Vaccine) and Johnson & Johnson (J&J) being used in South Africa is more effective on the delta variant than the beta variant of the corona virus. Experts have given information about this.
The beta variant first appeared in South Africa, which caused the second wave of COVID-19 in South Africa earlier this year (Coronavirus in South Africa). The case of the delta variant first appeared in India and due to this the third wave of the epidemic is going on in South Africa. In view of this, the lockdown and restrictions have been increased. In the third wave, the cases of death have also increased compared to the previous two waves.
Vaccines are effective on delta variants
South Africa’s Acting Health Minister Mamamoloko Kubayi told a news conference on Friday that experts say that based on both laboratory research and field studies, it has been found that these vaccines are effective on delta variants of the virus. ). Professor Glenda Gray, President and CEO of the South African Medical Research Council, said, ‘We have found that the J&J vaccine works better on the delta variant and as far as the delta and beta variants are concerned, it is the delta variant than the beta variant. But more effective.
No booster dose needed
Gray said that there is no need to even take a booster dose of the JAJ vaccine. Referring to the studies so far, he said that one dose was equally effective as compared to two doses of vaccine given to health workers during this period. Professor Penny Moore from the University of the Witwatersrand said that the current data shows that the vaccine currently used in South Africa is more effective on the delta variant than the beta variant. Pfizer’s vaccine produced more antibodies, while AstraZeneca did not. The data shows that AstraZeneca’s vaccine was not very effective on the beta variant, but if we talk about the delta variant, then Pfizer’s vaccine has been effective on this variant of the virus as well.
