Question
How does the administration of the hepatitis B vaccine at two months old affect its impact and effectiveness? Should the third dose still be administered at six months? Is it feasible to administer the polio vaccine at the same time as the hepatitis B vaccine at two months?
Answer
The hepatitis B vaccine should be administered in three doses, at 0, 1, and 6 months. According to the description, the second dose has been delayed by one month, which may affect the vaccine’s effectiveness. It is recommended that the third dose of the hepatitis B vaccine still be administered after six months. Administering the polio vaccine at the same time as the hepatitis B vaccine at two months may require evaluation and guidance from a healthcare professional.
