Cats should not be bathed while receiving vaccinations. This is because the vaccine is working during this period, and bathing could potentially render it ineffective or cause the cat to become ill. Vaccinations involve administering attenuated live vaccines to help the cat develop antibodies. During this time, the cat's immunity is lowered, so bathing is not recommended. Generally, cats can be bathed about a week after vaccination. Bathing immediately after vaccination may weaken the cat's immune system, leading to symptoms like colds, and could also cause stress, potentially worsening vaccine reactions. Bathing immediately after vaccination can also reduce the vaccine's effectiveness and still cause stress. 
Things to note when vaccinating cats:
1. Only healthy cats can be vaccinated; otherwise, the vaccination may be ineffective, fail, or cause other diseases to break out.
2. Do not bathe your cat two weeks before or after vaccination. If your cat has a cold, sneezes, has a runny nose, or is lethargic, it should not be vaccinated.
