Sadly making the disease worse isn't highly unlikely. I saw briefly an interview with a Japanese expert (but can't find it now) who says it should take 10 years to develop something like this and rushing a solution could change the virus into something worse. Also this from Scientific American ...It's a virus that causes a disease.
There are several different potential outcomes from any vaccine on a spectrum from making the disease worse(highly unlikely) to complete protection from the virus in most preventing onward transmission.
It is quite possible that the vaccine could protect you from severe forms of the disease but do less to prevent onward transmission. It is also possible that the vaccine gives you protection but not over a long period.
All viruses mutate some mutate to avoid the immune response successfully others have not no one knows whether that will happen with Covid, it is possible but by no means certain.
" Aside from questions of safety that attend any vaccine, there are good reasons to be especially cautious for COVID-19. Some vaccines worsen the consequences of infection rather than protect, a phenomenon called antibody-dependent enhancement (ADE). ADE has been observed in previous attempts to develop coronavirus vaccines. To add to the concern, antibodies typical of ADE are present in the blood of some COVID-19 patients. "
