When you arrive at Lowell General Hospital’s regional vaccination site, only one brand of COVID-19 vaccine will be offered to patients receiving their first dose.

The biggest difference is it is a one-dose vaccine – it does not require a second appointment. According to data from nearly 22,000 patients, the vaccine is 70% effective at providing full immunity from COVID-19, and virtually 100% effective at preventing hospitalization and death. Where it really counts, it’s just as effective as the other vaccines.
The best vaccine for you right now is the one you can get. The Johnson & Jonson vaccine does what really matters – keeping people out of the hospital and from dying, while decreasing transmission in the community. The faster we vaccinate our community, the faster we can get all of our lives back to normal.
According to the data, about 7 in 10 people will be fully protected. For those who don’t achieve full immunity, cases may be very mild, and the worst cases will have only moderate symptoms. Everyone is protected from severe illness, and that will significantly limit the ability of the virus to spread.
