Some members of the CDC advisory committee emphasised a scarcity of information Wednesday about how properly immunocompromised folks, these with underlying well being points and other people over age 75 would tolerate the vaccines and pointed to restricted proof about whether or not second doses would enhance safety.

Members additionally expressed concern about worth. GSK mentioned a single dose would value $200 to $295, and Pfizer estimated {that a} single dose would value $180 to $270. (These costs, although, don’t replicate what insured sufferers would pay.)

Along with older adults, RSV can pose a significant well being menace to infants. However two instruments to guard infants from the virus may grow to be accessible earlier than the autumn, as properly.
