A female asked:
Disclaimer

Is it safe to smoke medical marijuana 2 days after a Hepatitis A vaccine? I have read that marijuana decreases the immune response.

Define safe !: I cannot see that it would place you at any more risk than the drug effect would have anyway. Any diminished immune response would be minimal.

No effect: Marijuana does not interact with hepatitis A vaccine, typhoid vaccine or other vaccines.

No problem: I see no evidence either would interfere with the effectiveness of the vaccine. Whether alcohol or weed is a healthy pursuit is a separate issue.
