Mounting evidence that Vaccines mainly Pfizer and Moderna lose their effectiveness over time.

A British public health study has found that protection from either of the two most commonly used COVID-19 vaccines against the now prevalent Delta variant of the coronavirus weakens within three months.

It also found that those who get infected after receiving two shots of either the Pfizer-BioNTech (22UAy.DE) or the AstraZeneca (AZN.L) vaccine may be of greater risk to others than under previous variants of the coronavirus.

Based on more than three million nose and throat swabs taken across Britain, the Oxford University study found that 90 days after a second shot of the Pfizer or Astrazeneca vaccine, their efficacy in preventing infections had slipped to 75% and 61% respectively.

That was down from 85% and 68%, respectively, seen two weeks after a second dose. The decline in efficacy was more pronounced among those aged 35 years and older than those below that age.

The standard regimen for messenger RNA-based COVID-19 vaccines is two doses, but some governments, including Israel’s, have started administering third ‘booster’ shots. The latest study evaluated 1.1 million Israelis over the age of 60 who had received their first two doses at least five months earlier. Twelve or more days after receiving a third jab, participants were about 19.5 times less likely to have severe COVID-19 than were people in the same age group who had received only two jabs and were studied during a similar time period.

“It’s a very strong result,” says Susan Ellenberg, a biostatistician at the University of Pennsylvania in Philadelphia, who adds that the data might be the most robust she has seen in favour of boosters.
