sign in for the vaccine

To clarify, do you mean you want to create a form to offer vaccine services? If so, you can start building your form from scratch or use one of our templates here: https://www.jotform.com/form-templates/search/covid

Or if you mean you are looking for a form that offers vaccine services, unfortunately, we don't offer such. You may look for organizations within your area that offer the said services to sign up for one.
