What You'll Learn
Hepatitis B vaccine safety
Hepatitis B is a liver infection caused by the hepatitis B virus. It can range from a mild, short-term, acute illness lasting a few weeks to a serious, long-term, chronic infection. The best way to prevent hepatitis B is by getting vaccinated. Vaccines are available for infants, children, and adults. The hepatitis B vaccine is safe and effective, and it can provide a lifetime of protection.
The hepatitis B vaccine is a series of two or three shots, depending on the brand. The shots are typically given in the arm muscle. The first shot can be given at any time, but newborns should receive their first dose in the delivery room or within the first 12 hours of life if their mother is living with hepatitis B. The second shot is given at least one month after the first, and the third shot is given at least four months after the first and two months after the second. It is important to receive all doses of the vaccine to be fully protected. If a dose is missed, it is important to get the next dose as soon as possible.
As with any medicine, vaccines can have side effects. However, many people who get the hepatitis B vaccine experience no side effects at all. The most common side effects include injection site pain, soreness, or redness, headache, and fatigue, and they are usually mild and last 1-2 days. The Vaccine Adverse Event Reporting System (VAERS) monitors for potential vaccine safety problems, and healthcare providers and vaccine manufacturers are required by law to report certain adverse events following vaccination. A review of VAERS reports from 2005 to 2015 found no new or unexpected safety concerns with the hepatitis B vaccine.
There have been concerns and allegations about a possible link between the hepatitis B vaccine and various adverse events and autoimmune conditions, such as rheumatoid arthritis, diabetes, chronic fatigue syndrome, multiple sclerosis (MS), and lymphoblastic leukaemia. However, scientific studies have concluded that the hepatitis B vaccine does not cause MS or other autoimmune disorders, chronic fatigue syndrome, or chronic illness. The World Health Organization (WHO), the U.S. Centers for Disease Control and Prevention (CDC), and numerous medical societies state that there is no confirmed evidence that the hepatitis B vaccine causes any of the aforementioned conditions.

The CDC recommends the vaccine for all newborns, children up to 18, adults aged 19-59, and adults 60 and older with risk factors.
The hepatitis B vaccine is especially important for those with a higher risk of exposure to the virus. This includes:
- Infants born to mothers with hepatitis B
- Sexually active people who are not in a long-term, monogamous relationship
- People seeking treatment for a sexually transmitted infection
- People with end-stage renal disease, including dialysis patients
- Residents and staff of facilities for people with developmental disabilities

The hepatitis B vaccine is typically administered in a series of two to four shots, depending on factors such as age, vaccine type, and medical conditions. It is recommended for infants, children, adolescents, and adults, with varying guidelines for different age groups and risk factors.
For infants, the hepatitis B vaccine is often given within 24 hours of birth, and additional shots are administered at one month and four months after the initial dose. Children up to the age of 18 are also encouraged to receive the vaccine if they have not already done so.
The Centers for Disease Control and Prevention (CDC) recommends that all unvaccinated adults aged 19 to 59 receive the hepatitis B vaccine. Adults 60 and older may also receive the vaccine, especially if they have risk factors for hepatitis B infection.

How many hepatitis B vaccine shots are needed?
The number of hepatitis B vaccine shots a person needs varies depending on their age, health condition, and the vaccine brand. The hepatitis B vaccine is generally given in the arm as a two- or three-dose series.
The World Health Organization (WHO) recommends that all newborns receive the first dose of the hepatitis B vaccine within the first 24 hours of birth, also known as the "birth dose". The second dose is recommended at one month, and the third dose at six months of age. Completing the vaccine series beginning at birth will ensure protection against hepatitis B for life.
For adults, the number of recommended shots varies depending on age and health condition. The CDC recommends the hepatitis B vaccine for adults aged 19-59 and those 60 and older with risk factors for hepatitis B. Adults aged 18 and above can receive the HEPLISAV-B vaccine, which is given in two doses, one month apart. For adults on haemodialysis, four doses are recommended.
It is important to note that the hepatitis B vaccine series will not benefit those who currently have an HBV infection or have recovered from a past infection. However, the vaccine is recommended for those at high risk of infection due to their jobs, lifestyle, living situations, or country of birth.
In some instances, accelerated schedules may be necessary to ensure protection, such as before travel. These schedules may include additional booster doses at one year to provide maximum long-term protection.

Hepatitis B vaccine side effects
The hepatitis B vaccine is considered a safe and effective vaccine. It is made with an inactivated (dead) virus, so most types of the vaccine are even safe for pregnant people. However, mild side effects may occur in some cases. The most common symptom is redness, swelling, or soreness where the injection was given. Some people also experience headaches, nausea, vomiting, or fever. These effects are usually temporary and last for a few hours or days.
According to the CDC, common side effects of the hepatitis B vaccine occur in around 1 in 10 people who have it. Uncommon side effects may occur in 1 in 100 people, while serious side effects are rare, affecting only around 1 in 1,000 people. It is important to note that the occurrence of side effects does not necessarily indicate a direct result of the vaccination and could be due to other factors.
In rare cases, some people may have a severe allergic reaction to the vaccine, which can be life-threatening. Individuals with a history of severe allergic reactions to any previous dose of a hepatitis B vaccine or any of its ingredients should refrain from taking it. The hepatitis B vaccine must be administered by a medical professional who can monitor the individual for any allergic reactions.
The hepatitis B vaccine is crucial in preventing this potentially deadly infection. It is recommended for all newborns, children, adolescents, and adults, especially those at high risk of infection due to their age, lifestyle, living situations, country of birth, or medical conditions such as diabetes or end-stage renal disease.
