Researchers said the findings support the practice of mixing vaccines in certain circumstances. The U.K.-funded study found that mixing the Pfizer and AstraZeneca doses improved on the immune response provided by a two-dose regimen of the AstraZeneca shot. Alternating the shots provided less of a key immune response, however, than that provided by two doses of the Pfizer shot.

Delta Variant of Covid-19 Surges Across Unvaccinated Africa

JOHANNESBURG-The more-transmissible Delta variant of the coronavirus is surging across Africa, the continent with the least vaccines and weakest healthcare systems, feeding fears among epidemiologists and political leaders of a public-health disaster that could echo the tragedy that unfolded in India in the spring.

The speed of the takeover of the variant, which was first identified in India and is forcing governments around the globe to tighten restrictions on social and economic activities, has shocked health experts in Africa, a continent that-in part thanks to its younger population-has recorded fewer Covid-19 deaths than other regions. Some are warning that previous infection from another strain of the virus may not protect against Delta, leaving swaths of the population that were believed to be immune once again vulnerable.
