How do you gain active imunity to H1N1?

Active immunity to H1N1 can be gained through vaccination. H1N1 vaccines are available as both inactivated and live attenuated forms.

Inactivated vaccines are made from H1N1 viruses that have been killed. They are safe for most people, but they can cause mild side effects such as soreness, redness, and swelling at the injection site. Inactivated H1N1 vaccines are available in two doses, which are given 2 to 4 weeks apart.

Live attenuated vaccines are made from live H1N1 viruses that have been weakened so that they do not cause disease. They are more effective than inactivated vaccines, but they can also cause more side effects, such as fever, chills, muscle aches, and fatigue. Live attenuated H1N1 vaccines are available in one dose, which is given through a nasal spray.

Both inactivated and live attenuated H1N1 vaccines are effective in preventing H1N1 infection. The best vaccine for you will depend on your individual health status and risk factors. If you are not sure which vaccine is right for you, talk to your doctor.
