mRNA Vaccines May Offer Lasting Protection, Study Finds

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.

San Diego's mayor and lawmakers call for end to COVID restrictions at the US-Mexico border

A group of southern California lawmakers, including San Diego's mayor, called for an end to pandemic restrictions along the border with Mexico as part of an effort to boost the local economy.

"As the rate of COVID-19 cases continue to plummet, and other restrictions have been lifted, I see no reason to continue selective restrictions that impact our cross-border community," mayor Todd Gloria said in a press release.

The border has been closed to non-essential travel since March 2020. The Dept. of Homeland Security last Sunday extended through July 21 those restrictions for all land or ferry crossings into the US.
