I am 30 year old male. I have health anxiety and I had panic attacks from october 2020 to october 2021. The palpitation symptoms were almost reduced after 1 year. But, still heart pounds when bloated and or urge to have a bowel movement. I have not yet vaccinated for covid due to fear. But, I took the tetanus vaccine 6 months ago and have also taken the influenza vaccine and rabies vaccine 10 years ago. My question is, should I take the cavity vaccine now? Or wait for some universal covid vaccine or variant specific covid vaccine or any other update regarding the prevention of cavity? Other conditions that I suffer are, sinusitis, eustachian tube dysfunction, gastritis, slight varicose vein, kidney stone, dust allergy for eyes, dry skin, pimples on back of body, sometimes have noticed itching and hives on skin after dealing with invisible small insects present in environment like bugs or sometimes from opening dried coconut husk etc. Is there any other alternative method to prevent cavity other than covid vaccine?
