When should I get vaccinated?
CDC recommends that people get vaccinated against flu soon after vaccine becomes available, if possible by October.
It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against the flu.
Doctors and nurses are encouraged to begin vaccinating their patients soon after vaccine becomes available, preferably by October so as not to miss opportunities to vaccinate. Those children aged 6 months through 8 years who need two doses of vaccine should receive the first dose as soon as possible to allow time to get the second dose before the start of flu season. The two doses should be given at least four weeks apart.
What flu viruses does this season’s vaccine protect against?
Flu vaccines are designed to protect against the main flu viruses that research suggests will be the most common during the upcoming season. Three kinds of flu viruses commonly circulate among people today: influenza A (H1N1) viruses, influenza A (H3N2) viruses, and influenza B viruses.
All of the 2015-2016 influenza vaccine is made to protect against the following three viruses:
an A/California/7/2009 (H1N1)pdm09-like virus
an A/Switzerland/9715293/2013 (H3N2)-like virus
a B/Phuket/3073/2013-like virus. (This is a B/Yamagata lineage virus)
Some of the 2015-2016 flu vaccine is quadrivalent vaccine and also protects against an additional B virus (B/Brisbane/60/2008-like virus). This is a B/Victoria lineage virus.
Vaccines that give protection against three viruses are called trivalent vaccines. Vaccines that give protection against four viruses are called quadrivalent vaccines.
I have purchased Fluzone quadrivalent for the adult Sandwich flu clinics.
