What you need to know about the flu shot this year, no matter who pays

What is the effectiveness of influenza vaccines?

Efficiency varies every year. Because it takes at least six months to make and distribute the plans that become available In September, scientists need to guess the strains that will circulate, and therefore what to include in a vaccine, well in advance. Meanwhile – and even during the production of vaccines – circulating viruses can mutate, decreasing the effectiveness of the chosen vaccine. It is an imperfect science.

"We are doing our best," said Dr. Offit, who also sits on the advisory board of the Food and Drug Administration, which recommends which strains to include. "But you are trying to predict what will happen in six months."

Sometimes, he says, the experts are wrong to guess. In 2014-15 season, the vaccine was only 19% effective. During the last influenza season, the overall efficacy of influenza A and B vaccine was estimated at 40%. In other words, it would reduce the risk of getting a cure for the flu by 40%, according to the Washington Health Center.

Will I have to pay for my vaccine?

Most people with affordable health care coverage are entitled to a flu shot with no co-payments or co-insurance. Make sure to check with your insurer; you may need to be vaccinated by your doctor or specific providers.

Influenza vaccines for Medicare beneficiaries are covered by Part B; Beneficiaries pay nothing until the doctor or other provider accepts Medicare.

Medicaid covers influenza vaccines for children and young adults under the age of 20. Adults eligible for Medicaid are also covered, although this may vary from state to state.

If you are not covered, prices vary depending on the type of vaccine. Walgreens said that more than 90% of vaccinated clients are covered by insurance. Those who are not can expect to pay $ 40.99 for a quadrivalent stroke, while both options for those 65 and over – the high dose stroke and the one with adjuvant – each costs $ 69.99.

At CVS, the quadrivalent is $ 41.99 and the shot at high $ 66.99.

Rite Aid is offering a standard trivalent flu vaccine at $ 34.99 and a quadrivalent vaccine at $ 39.99. For people over 65, he offers Fluad, which includes an adjuvant, for $ 74.99.
