BUDAPEST — Officials in Hungary are urging people to trust in the vaccines already approved by the country ahead of a planned rollout Wednesday of a COVID-19 vaccine developed in China.

LONDON (AP) — Two U.K. studies released Monday showed that COVID-19 vaccination programs are contributing to a sharp drop in hospitalizations, boosting hopes that the shots will work as well in the real world as they have in carefully controlled studies.

Preliminary results from a study in Scotland found that the Pfizer-BioNTech vaccine reduced hospital admissions by up to 85% four weeks after the first dose, while the Oxford-AstraZeneca shot cut admissions by up to 94%. In England, preliminary data from a study of health care workers showed that the Pfizer vaccine reduced the risk of catching COVID-19 by 70% after one dose, a figure that rose to 85% after the second.

LONDON (AP) — The British government declared Sunday that every adult in the country should get a first coronavirus vaccine shot by July 31, at least a month earlier than its previous target, as it prepared to set out a “cautious” plan to ease the U.K.’s lockdown.
