Details for: COMIRNATY Omicron XBB.1.5

COMIRNATY Omicron XBB.1.5 is a vaccine used to provide protection against COVID-19 disease caused by the SARS-CoV-2 virus.

COMIRNATY Omicron XBB.1.5 can be given to people 6 months of age and older.

The safety and effectiveness of COMIRNATY Omicron XBB.1.5 for individuals 6 months of age and older are based on studies which evaluated the primary series and booster vaccination with COMIRNATY and supported by studies which evaluated a booster dose of COMIRNATY Original & Omicron BA.4/BA.5 in individuals 6 months of age and older. Data obtained with COMIRNATY and COMIRNATY Original & Omicron BA.4/BA.5 are relevant to COMIRATY Omicron XBB.1.5 because these vaccines are manufactured using the same process.

The vaccine causes our body to produce protection (such as antibodies) that prevent the COVID-19 virus from entering our cells to make us sick. The vaccine uses a new method (messenger RNA - mRNA, the genetic code for a piece of the virus) to help our bodies make protection against the virus. The vaccine is given by injection with a needle in the upper arm.

You cannot get COVID-19 from the vaccine.

As with any vaccine, COMIRNATY Omicron XBB.1.5 may not fully protect all those who receive it. Even after you/your child have had the vaccine, continue to follow the recommendations of local public health officials to prevent spread of COVID-19.

You/your child should not receive COMIRNATY Omicron XBB.1.5 if:

• you/your child are allergic to any of the ingredients in this vaccine (see What are the ingredients in COMIRNATY Omicron XBB.1.5?)
• you/your child had a severe allergic reaction after a previous dose of COMIRNATY, COMIRNATY Original/Omicron BA.1 or COMIRNATY Original & Omicron BA.4/BA.5.
• you/your child have any symptoms that could be due to COVID-19. Talk with your/your child’s healthcare professional about your/your child’s symptoms and getting a COVID-19 test. Your/your child’s healthcare professional will advise you when you/your child are able to receive the vaccine.
