No, and even if the Lyme vaccine is approved, it won't replace tick control. The vaccine only covers one tick-borne disease, and with only 70% efficacy.
If you've seen the headlines about the Pfizer and Valneva Lyme disease vaccine and wondered whether professional tick treatment is about to become unnecessary, that’s a reasonable question to ask. The prospect of a vaccine is incredibly encouraging. But even in a best-case scenario, tick control will still be important.
The vaccine candidate is called LB6V, and it’s shown about 73% efficacy in Phase 3 trials as of March 2026. That’s a good outcome for a vaccine, outpacing even annual flu vaccines in terms of efficacy—and those save thousands of people from hospitalization and death every year. But it also means that three in ten vaccinated people who encounter Lyme-causing bacteria could still fall ill. The vaccine also requires multiple doses over time, and no FDA approval timeline has been confirmed. Even under optimistic projections, widespread public availability will take time.
Ticks also carry more than Lyme disease. Blacklegged ticks in the Southern Westchester area also transmit the pathogens responsible for anaplasmosis, babesiosis, and Powassan virus. The Lyme vaccine does nothing against any of these. Babesiosis can be severe in older adults and immunocompromised individuals, and Powassan virus, while rare, can cause serious neurological damage. A single tick can carry more than one pathogen simultaneously.
There’s also the quality-of-life factor to consider. Even if you were completely immune to all possible tick-borne diseases, you probably still wouldn’t want ticks crawling on you, your kids, or your pets. Vaccines reduce disease risk, but they don’t reduce the amount of ticks in your yard or bites on your leg.
If you’re worried about tick-borne disease, Mosquito Squad of Southern Westchester can help you reduce your risk with tick control treatments. These treatments work by reducing the tick population on your property throughout the season. Whether a vaccine arrives next year or five years from now, fewer ticks in your yard means fewer bites and more time outside without checking your ankles every ten minutes.
