Is there a vaccine?

Yes! You can get vaccinated for Hepatitis A and B at the same time. You will receive three shots over six months, which will protect you for up to 25 years. If you are considered to be at “high-risk” by Public Health, i.e. if you’re a gay male, an injection drug user, a sex worker, or a community worker providing services to a “high risk” population, you can get vaccinated for free. If you don’t fit into these categories, it costs approximately $20 per shot.

What are the long term effects?

The vast majority of people get better after having been sick for about six months. Hepatitis A does not become a chronic infection.

How is it transmitted?

Hepatitis A is found in the feces, (poop) of someone who is infected. 
It can be transmitted the following ways:

Feces to mouth

Feces can be transmitted to your mouth by tainted hands. Wash your hands after going to the toilet or changing a diaper. Likewise, unclean dishes or utensils may have traces of poop on them, so clean them well.

Contaminated water or ice cubes
You likely won’t find Hepatitis A in Canadian drinking water. If you travel to countries without proper sewage treatment, don’t put ice in your drinks, and drink sealed, bottled water. Wash imported fruit and vegetables well before you eat them.

Rimming

When you do analingus (licking an anus or asshole, rimming) you can put a latex barrier between your mouth and the asshole. If you are also fingering an asshole, keep those fingers out of your mouth until you’ve washed them.
