But diapers aren't meant to safeguard against vapours or other elements in tear gas, so neither will a surgical mask. The N95 or X301 do not protect the wearer from pollution. Yu says the respirators block containments in particle form only, not gases like ozone and nitrogen dioxide.
Flu vaccine is an inactivated vaccine, meaning that it contains killed influenza virus. The killed influenza virus is injected into muscles or skin and stimulates the immune system to produce an immune response (antibodies) to the influenza virus.
A flu shot is the best way to protect kids from the flu and problems that come along with it. There are two types of vaccines: one is given as a shot and the other as a spray that your child breathes in. You should only give the spray to kids over 2 who donât have chronic medical conditions. That means kids under 2 should get the flu shot vaccine. The vaccine your child gets in a shot is made from dead influenza virus. It can't cause the flu. When your childâs immune system comes in contact with the vaccine, it creates special tools called antibodies that help it fight the virus.
