According to a Pfizer study, the vaccine from the US and German Biontech loses its effectiveness within six months: it drops from 96% to 84% according to the data published in the preprint not yet peer-reviewed. Stat News reports that according to an ongoing Pfizer study of more than 44,000 people, the vaccine‘s effectiveness in preventing any Covid-19 infection that causes even minor symptoms appeared to decrease by an average of 6% every two months after administration. . Pfizer’s study, which enrolled volunteers in Europe and the Americas, does not consider whether the vaccine is less effective against the Delta variant. These data reopen the theme of the third dose. The pharmaceutical company’s head of research and development said he expects the third dose to be “a little longer lasting” than the second dose.
Vaccine obligation for Google and Fb employees
Google and Facebook have announced that their employees who will return to work in the presence, in the offices, will have to be vaccinated against Covid-19. Spikes in infections due to the Delta variant of the virus have increased concerns in the United States, where 611,000 people have died as a result of the pandemic. Google will make its campuses banned for unvaccinated employees and extend home-based smartworking until October 18, CEO Sundar Pichai reported. “Anyone who comes to work on our campuses will need to be vaccinated,” Pichai explained in a blog post. “We are implementing this policy in the United States in the coming weeks and will extend it to other regions in the coming months.” “I hope these steps will give everyone more peace of mind when the offices reopen,” Pichai added. “Seeing the ‘googlers’ together in the offices over the past few weeks has filled me with optimism and I’m looking forward to better days.” “While the virus continues to emerge in many parts of the world, it is encouraging to see very high vaccination rates for our Google community in areas where vaccines are widely available,” Pichai said. “This is a big reason why we felt comfortable opening some of our offices to employees who wanted to return soon.” Facebook has released a very similar announcement, stating that, when the offices reopen, only vaccinated workers will be welcomed. “We will ask anyone who comes to work on one of our US campuses to be vaccinated,” said Lori Goler. “We will have a procedure for those who cannot be vaccinated for medical or other reasons and will evaluate our approach in other regions as the situation evolves.”
