With more than 6,000 people infected and the state death toll from whooping cough at 10 babies, readers have asked the Los Angeles Times where they can get vaccinated against the disease, also known as pertussis.

Whooping-cough immunizations can be had at doctors’ offices and local pharmacies. A random check of five pharmacies in the Los Angeles area found that the shot for adults — Tdap, which protects against tetanus and diphtheria as well as pertussis — costs about $60 or $65. But not all of them had the immunizations on hand. So call the pharmacy first to check.

Some pharmacies take insurance, but check with your insurance company to determine whether vaccines are covered by your plan and whether they will be covered at a pharmacy.

For senior citizens, some doctors’ offices and pharmacies are erroneously giving outdated information that seniors cannot be inoculated. You can print out a correct statement by the California Department of Public Health that recommends that seniors get the Tdap shot. Or contact your local county or city public health department, listed below.

For seniors, Medicare covers Tdap inoculation as a “Part D” drug and you can get one at an in-network pharmacy or an in-network doctor’s office. Some doctors and insurance companies have been giving wrong information about whether Medicare covers Tdap for seniors. Show them the statement by Medicare confirming the coverage.

If you don’t have insurance or cannot afford the vaccine, local county and city health departments sometimes offer free or discounted vaccines. A list of resources is available below.
