Daily US Times: The AstraZeneca and Pfizer coronavirus vaccines are highly effective against the Indian variant of coronavirus after two doses, a study by Public Health England has found.

Two jabs of either vaccine give a similar level of protection against symptomatic disease from the Covid-19 variant as they do for the Kent one.

However, both Covid-19 vaccines were only 33% effective against the Indian variant three weeks after the first dose.

This compared with fifty percent effectiveness against the Kent variant.

Public Health England said the vaccines are likely to be even more effective at preventing hospital admission and deaths.

The UK Health Secretary Matt Hancock said the findings made him “increasingly confident” that the government was on track for the final stage of easing restrictions in England.

Pfizer’s coronavirus vaccine was found to be 88% effective at stopping symptomatic disease from the Indian variant two weeks after the second dose, compared with 93% effectiveness against the Kent variant.

The AstraZeneca vaccine was 60% effective against the Indian variant, compared with 66% against the Kent variant.

Public Health England (PHE) said the difference in effectiveness between the AstraZeneca and Pfizer vaccines after two doses may be explained by the fact that rollout of second doses of AstraZeneca was later than for the Pfizer vaccine, which was approved first.

PHE said that other data shows it takes longer to reach maximum effectiveness with the AstraZeneca vaccine.

Some 12,675 genome-sequenced cases were included in the Public Health England study, which took place between 5 April and 16 May.
