mRNA Vaccines May Offer Lasting Protection, Study Finds

Mon, 2021-06-28 09:50 — mike kraft

A study finds that the Pfizer and Moderna vaccines could offer protection for years

The vaccines made by Pfizer-BioNTech and Moderna set off a persistent immune reaction in the body that may protect against the coronavirus for years, scientists reported on Monday.

The findings add to growing evidence that most people immunized with the mRNA vaccines may not need boosters, so long as the virus and its variants do not evolve much beyond their current forms — which is not guaranteed. People who recovered from Covid-19 before being vaccinated may not need boosters even if the virus does make a significant transformation.

“It’s a good sign for how durable our immunity is from this vaccine,” said Ali Ellebedy, an immunologist at Washington University in St. Louis who led the study, which was published in the journal Nature.

The study did not consider the vaccine made by Johnson & Johnson, but Dr. Ellebedy said he expected the immune response to be less durable than that produced by mRNA vaccines.

Covid is already deadlier this year, variants are spreading but many in U.S. think the pandemic is over.

Thu, 2021-06-24 14:06 — mike kraft

Covid is already deadlier this year than all of 2020. So why do many in U.S. think the problem’s over? In the global scramble for Covid-19 vaccines, high-income countries, predictably, have sought to secure stocks for their own populations first. Sam Meredith CNBC

As the U.S. pushes ahead with its reopening, easing mask mandates and lifting public health restrictions, much of the rest of the world is seeing an alarming surge in the number of Covid-19 infections and deaths.

Doubts raised about Chinese COVID vaccines used in several countries

Wed, 2021-06-23 09:55 — mike kraft

They relied on Chinese COVID vaccines. Now they’re battling outbreaks. Recent infections in Mongolia, Bahrain, Chile and the Seychelles suggest that the Chinese vaccines they use may not be very effective at preventing the spread of the coronavirus, particularly the new variants. The Seattle Times

Mongolia promised its people a “COVID-free summer.” Bahrain said there would be a “return to normal life.” The tiny island nation of the Seychelles aimed to jump-start its economy.
