Study: These 2 Types of Vaccines Are Effective Against India’s Covid-19 Variant B.1.617 Pages All

KOMPAS.com – Two doses of the Covid-19 vaccine are effective against the coronavirus variant B.1.617, the fast-spreading strain first identified in India.

According to information from British health authorities on Saturday (May 22, 2021), the two vaccines are vaccines from Pfizer and AstraZeneca. Its effectiveness is almost similar to the B.1.1.7 variant or the variant often referred to as the Kent variant.

Both vaccines were highly effective against the B.1.617 variant after two doses of injections.

Reported by Reuters, Sunday (May 23rd, 2021), three weeks after the first dose, both vaccines are only 33 percent effective against the Indian variant.

Its effectiveness is less than the effect against the Kent variant – variant B.1.1.7, which was first discovered in Great Britain – which is up to 50 percent effective.

This means that it is very important to get two doses of the Covid-19 vaccine.

In a research report published in the journal Public Health England, Both vaccines are likely more effective at preventing Covid-19 patients from being hospitalized and dying.

“I am increasingly convinced that the UK is on the right track as these data show that a two-dose vaccine is also effective against the Indian variant. And we all know a vaccine is the way out, ”said Health Secretary Matt. Hancock.

Reported by BBC, Sunday (May 23, 2021), the Pfizer vaccine was 88 percent effective in stopping symptomatic disease (symptomatic) of the Indian variant two weeks after the second dose.

Compared to the effectiveness against the Kent variant B.1.1.7, the effectiveness of Pfizer reaches 93 percent.

Meanwhile, injection of the AstraZeneca vaccine after the second dose was 60 percent effective against the Indian variant.

Compared to the Kent variant, the effectiveness is 66 percent.

“Other data suggests that the AstraZeneca vaccine may take longer to achieve maximum effectiveness,” said PHE.

Approximately 12,675 cases of genome sequencing were included in the study, which took place between April 5 and May 16.

Only 1,054 of these cases were of the Indian variant known as B.1.617.

When the virus changes, infection protection is the first thing to be missed.

The study looked at data across all age groups as of April 5, the period when the Indian variant first appeared in the UK.

“There is not enough data to estimate how effective the vaccine is against patients who are seriously ill with the B.1.617 variant,” said PHE.

Dr. Jamie Lopez Bernal, consulting medical epidemiologist at PHE and lead author on the study, said the data from the first vaccine dose are more confident than the second.

“There are more people who have been vaccinated with one dose. I think we classify it as moderate safety on the first dose but low confidence on the second dose,” said Bernal.

Prof. Susan Hopkins, PHE director for strategic response to Covid-19, said the trend in the data is pretty clear and is going in the right direction.
