After federal health officials made abrupt changes to US Covid-19 vaccine recommendations for pregnant women last month, there’s new confusion and uncertainty about who can get the shots — and some reports that patients were turned away when they tried to get vaccinated.

The safety of approved mRNA vaccines is well-established and, as with other vaccines, continues to be monitored by multiple surveillance systems.

In recent years COVID shots joined flu shots as an annual offering at most neighborhood pharmacies. But the current administration has thrown that into uncertainty

The FDA's approval was based on a study of 11,400 people age 12 and older that compared the new low-dose vaccine with Moderna's existing vaccine. It found the new vaccine was safe and was at least as effective - and more by some measures - than the original shot, the company said.

Now that Covid vaccines are no longer recommended for healthy children and pregnant people, boosters could be a lot more expensive this fall. Here’s why.

Alberta will begin charging most residents for COVID-19 vaccines later this year. Starting in the fall, the province says they will be rolling out a COVID vaccine program and any people who are not immunocompromised or on social programs will need to pay for the shot.

The Food and Drug Administration has approved Moderna's new COVID-19 vaccine, days after the federal government tightened vaccine standards for the virus.

Three of the health secretary’s picks to replace fired members of an influential panel that sets U.S. vaccine policies have filed statements in court flagging concerns about vaccines.
