Mixing different types of Covid vaccines can boost immune response, study finds Some European countries have started offering alternatives to AstraZeneca as a second shot after the vaccine was linked to rare blood clots. NBC News

A mixed schedule of vaccines where a shot of Pfizer's Covid-19 vaccine is given four weeks after an AstraZeneca shot will produce better immune responses than giving another dose of AstraZeneca, an Oxford study said on Monday.

Confronting a legacy of scarcity in U.S. funding for public health - STAT Decades of underfunding public health have left Americans vulnerable to Covid-19 and future calamities that are just around the corner. Patrick Skerrett STAT

Public health in America is in crisis, a sad fact that the Covid-19 pandemic has made impossible to ignore.

As the country’s vaccination campaign slows and doses go unused, it has suddenly become clear that one of the biggest barriers to mass immunity will be persuading skeptical young adults of all backgrounds to get shots. Federal officials expressed alarm in recent days about low vaccination rates among Americans in their late teens and 20s, and have blamed them for the country’s all-but-certain failure to reach President Biden’s goal of giving 70 percent of adults at least an initial dose by July 4.

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.

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.
