Now for Some Hopeful News

We gave you the bad news about eating fried foods, which really is nothing very new.  But there was some hopeful news last week that we want to pass along.

According to the Associated Press, the AstraZeneca's COVID-19 vaccine, which is being used in Great Britain, does more than prevent people from falling seriously ill — it appears to reduce transmission of the virus and offers strong protection for three months on just a single dose, researchers said last week in an encouraging turn in the campaign to suppress the outbreak.

The news came from preliminary findings from Oxford University, a co-developer of the vaccine.  The research could also bring scientists closer to an answer to one of the big questions about the vaccination drive: Will the vaccines curb the spread of the coronavirus?

It is not clear what implications, if any, the findings might have for the two other major vaccines being used in the U.S., Pfizer's and Moderna's.

The research appears to be good news in the desperate effort to arrest the spread of the virus and suggests a way to ease vaccine shortages and get people vaccinated more quickly.

The makers of all three vaccines have said that their shots proved to be anywhere from 70% to 95% effective in clinical trials in protecting people from illness caused by the virus. But it was unclear whether the vaccines could also suppress transmission of the virus — that is, whether someone inoculated could still acquire the virus without getting sick and spread it to others.

As a result, experts have been saying that even people who have been vaccinated should continue to wear masks and keep their distance from others.

Oxford's study, however, found that the vaccine not only prevented severe disease but appeared to cut transmission of the virus by two-thirds. The study has not been peer-reviewed yet.

Pfizer and Moderna also are studying the effect of their vaccines on asymptomatic infections.
