There is a lot of information about coronavirus vaccines out there, and some of it seems vague or contradictory. We talked to experts to help answer some of the most common and confusing questions.
The COVID-19 vaccine strategy may be shifting toward Americans getting yearly vaccinations, like many do with annual flu shots.
The new shots from Moderna and Pfizer-BioNTech target both the original strain of the coronavirus and the omicron BA.4/BA.5 subvariants that most people are catching now.
The vaccine maker alleges that its rivals Pfizer and BioNTech used some patented features of its mRNA technology to develop their COVID vaccines.
Health care providers hope the Novavax COVID-19 vaccine will appeal to people who haven't recieved any doses of previous vaccine iterations.
Adults who haven't gotten any COVID-19 shots should consider the new option, the agency said Tuesday. The spike protein vaccine is more typical than the mRNA types being broadly used against COVID.
A committee of experts voted unanimously to recommend that the Food and Drug Administration authorize COVID-19 vaccines from Moderna and Pfizer-BioNTech for children as young as 6-months-old.
The variants — BA.2.12 and BA.2.12.1 — have been detected in New York and other states as well as 5 other countries. One has a mutation that seems to give it an edge in evading the immune system.
My 6-year-old has been exposed to SARS-CoV-2 at least four times and never tested positive. Many people fall into that category. Researchers have theories about why they've been able to ward it off.
The vaccinators are going door-to-door in what the government is calling an unprecedented effort, toting coolers with a mix of COVID vaccine types.
The consensus has been that Pfizer and Moderna are most protective. But a study looking at 5 vaccines — including Russia's Sputnik V and two Chinese types — offers an unexpected finding.
Cuba has one of the world's highest COVID vaccination rates, with more than 85% of the nation fully immunized and kids as young as 2 getting inoculated. And it's done so using homegrown vaccines.
Though people who are vaccinated and boosted appear to be better protected against omicron, the highly contagious variant has still led to breakthrough cases and a surge in infections worldwide.
Hit hard by the pandemic, the Philippines has vaccination rates far lower than neighbors like Vietnam and Cambodia. Here's how the country is trying to up its numbers.
CDC Director Rochelle Walensky gave the green light to boosters just hours after a panel of vaccine advisors voted unanimously to recommend boosters for anyone 18 and older.
