The Centers for Disease Control and Prevention (CDC) said Thursday it was recommending that the nation’s more than 40 million adults get the two doses of the vaccine for people who have been vaccinated, after the government’s own review found that some strains of the coronavirus had the potential to cause serious health problems.
The recommendation, which was issued in a report to Congress, comes as the agency says the vaccine is safe for most people, but for some people, including pregnant women, those with weakened immune systems and people with chronic medical conditions, the risk is greater.
It also comes as scientists say there is no evidence that people who were already vaccinated are any more at risk of getting the virus.
Some experts are saying that the recommendation could lead to a resurgence of the virus, even if the vaccine were never widely distributed.
But other experts say that the vaccine would have no lasting impact if the current vaccination rates continue to decline.
The report, issued Thursday, is based on data from the Centers for Medicare and Medicaid Services (CMS), which monitors the use of prescription medications to prevent and treat diseases, including cancer.
It is a major document that has become a key part of the fight against the coronas.
The data are shared with the CDC and the U.S. Department of Justice to help determine how much and when the government should spend.
The CDC, which is funded by the federal government, released the report on Thursday, after a House subcommittee approved the bill to increase the amount of money for the program.
A vote is expected Thursday in the House of Representatives.CMS said that the agency was reviewing the CDC’s recommendations, and if they were changed it would be “reassuring to those of us who rely on this vital health information to make critical health decisions.”
The agency said the vaccine can be administered to up to three doses for adults age 21 and older, and to children age 6 to 11, and for pregnant women and women with pre-existing conditions.
The agency also said that it has seen no evidence to suggest that people younger than 21 are at increased risk of contracting the virus or getting sick from it, and that people with weakened immunity could still be exposed to the virus even if they are vaccinated.
The agency said people with pre-, moderate- or severe-to-serious medical conditions would not benefit from getting the vaccine.
The FDA has approved the two vaccines, but the vaccine manufacturers and others say the new administration could make it harder to get the vaccine if it moves to the market.
The vaccine is the second time the CDC has released a report on the vaccine, which came after the agency said that some vaccine strains of coronaviruses pose a threat to public health.
The first report came in November 2015, and the CDC reported in March that some vaccines have the potential of causing serious health conditions or death.
The government has been under fire in recent weeks for not doing enough to address the threat from coronaviral diseases, which have spread across the globe in the past year.
On Tuesday, the Centers of Disease Control, which has been responsible for public health, warned that the U,S.
faces an increasing threat from a resurgence.
A group of lawmakers, including Republican members of the House Committee on Oversight and Government Reform, sent a letter to the FDA, asking the agency to revise its recommendations on the coronaval vaccine, and in particular to make the vaccine easier to get.
“This report does not provide an accurate picture of the public health risks associated with the two coronaviroclavirus vaccines,” the lawmakers wrote.
“We urge the FDA to reconsider its recommendations and to reconsider recommending the two vaccine strains for use.”
The FDA on Thursday said that, based on the CDC analysis, it will not revise its recommendation for the two dose vaccine.
