Can A Smallpox Vaccine Be Prevented In A Single Dose?
Hello doctor, I am 26 years old and have never had smallpox, I want a smallpox vaccine (varivax vaccine) because by chance at my home there is smallpox and I am afraid of contracting it. Can one dose of vaccine prevent transmission? or have to wait until the second dose? thank you
Hello, thank you for the question to HealthReplies.com
Basically if someone in your house already has symptoms of chickenpox (varicella), then there is a possibility that you have contracted the varicella virus as well. Varicella virus can be transmitted since 2 days before the appearance of rashes on the skin until the rash has dried. When a person is infected with the varicella virus, symptoms of varicella will only appear 10-21 days after exposure.
You may still do the vaccine. Varicella vaccine is recommended to be given 2 times. Administration of 1 effective dose protects a person from varicella by 85% (but almost 100% effective protects against severe varicella infection), while administration of 2 effective doses protects someone from varicella by 98% (and 100% is effective protecting from severe varicella). Severe varicella means that the symptoms of varicella are not limited to skin lesions, but can affect the brain (encephalitis) and the lungs (pneumonia).
So much information from me, hopefully enough answer
