June 14, 2021 07:31PM "If I've waited to get the vaccine, will there still be chances to get it in the future? How can I get it in the upcoming months?"Â In the past 6 weeks, we saw a dramatic shift from the Covid-19 vaccine being hard to obtain to it being readily available at both small clinics and mega sites. As these mega sites start to close, a question Iâm asked is will the vaccine still be available in the future. This question usually comes from someone who is hesitant about receiving at this time and either wants to wait to study the vaccine more, wants to see if the vaccine has side effects on other people or see the effectiveness of the vaccine.
