The recent global outbreak of mpox, previously known as monkeypox, has raised concerns about its transmission and prevention. Mpox is a viral illness caused by the monkeypox virus, which belongs to the Orthopoxvirus genus, including smallpox, cowpox, and vaccinia. While the chickenpox vaccine does not provide immunity against mpox, the smallpox vaccine can offer protection. This is because mpox is closely related to the smallpox virus, and the smallpox vaccine can provide up to 80% protection, depending on individual immune systems. However, the level of protection from previous smallpox vaccination may not be lifelong, and newer specific vaccines like JYNNEOS, a 2-dose vaccine, are recommended for stronger protection against mpox.
| Characteristics | Values |
|---|---|
| Chickenpox vaccine helps against monkeypox | No, chickenpox is not a member of the pox family of viruses, so having had chickenpox or the vaccine does not make you immune to monkeypox. However, the smallpox vaccine can offer protection against monkeypox, as they are related viruses. |
| Monkeypox vaccine | The JYNNEOS vaccine is a 2-dose vaccine developed to protect against monkeypox and smallpox. |
| Smallpox vaccine | The smallpox vaccine can offer protection against monkeypox, but it may not be lifelong. |
| High-risk groups | High-risk groups are advised to take the monkeypox vaccine as newer specific vaccines are limited. |
| Timing | If the vaccine is received within four days of exposure, it can prevent monkeypox from causing disease. If received within two weeks of exposure, it can prevent the infection from becoming severe. |
| Administration | The vaccine can be given subcutaneously or intradermally, with two doses recommended for the best protection. |

Chickenpox is not a member of the pox family viruses
Chickenpox is caused by the varicella-zoster virus, which belongs to the herpes family of viruses. Despite its name, chickenpox is not a member of the pox family of viruses. Chickenpox was not differentiated from smallpox until the late 19th century. The first documented use of the term "chicken pox" was in 1658, and various explanations have been proposed for the use of "chicken" in the name, including the relative mildness of the disease and the resemblance of the rash to chickpeas or chicken pecks.
Chickenpox is a highly contagious disease that usually affects children. It is characterised by an itchy, blister-like rash that can spread across the body. The rash typically lasts about 4 to 7 days and can result in children missing school or childcare. In adults, the rash may be more widespread and accompanied by a longer fever, and there is a higher risk of complications such as varicella pneumonia.
The chickenpox vaccine is the best way to prevent the disease. The vaccine is recommended for everyone, including children, adolescents, and adults, who have never had chickenpox or received the vaccine. It is given in two doses, with the second dose administered 4 weeks after the first. Since the introduction of the vaccine, there has been a significant decrease in chickenpox cases, complications, hospitalizations, and deaths.
While the chickenpox vaccine protects against chickenpox and its complications, it does not provide immunity against monkeypox. Monkeypox is a separate virus from chickenpox, and the two diseases are not related. Existing vaccines against smallpox, a closely related virus to monkeypox, can be effective in preventing monkeypox infection. However, due to the cessation of smallpox vaccination in the past 50 years, a large portion of the population lacks immunity to smallpox and, by extension, monkeypox.

Smallpox vaccines can offer protection against monkeypox
Monkeypox, or mpox, is an emerging threat to humans since a new outbreak in May 2022. It is believed that the cessation of smallpox vaccination campaigns in the 1970s and 1980s is one of the leading causes of the recent mpox outbreak. As a result, nearly half of the current US population doesn't have immunity to smallpox or mpox.
Smallpox vaccines have been found to offer protection against mpox. A systematic review and meta-analysis of 37 studies with 57,693 participants showed that mpox infection rates were significantly lower in the smallpox-vaccinated group compared to the unvaccinated group. The data also revealed that smallpox vaccination effectively reduced the risk of severe mpox infection. Furthermore, the smallpox vaccination decreases the risk of mpox by 5.2-fold, and the immunity provided by prior smallpox vaccination is long-lasting.
While the JYNNEOS vaccine, a 2-dose vaccine developed to protect against mpox and smallpox, provides stronger protection against mpox, the number of doses of the smallpox vaccine does not seem to have a significant effect on mpox. Additionally, people who have been previously vaccinated against smallpox have higher immunity and tend to experience fewer serious adverse events after vaccination than those receiving the smallpox vaccine for the first time.
It is important to note that getting vaccinated within four days of exposure to mpox can help prevent the disease. Vaccination within two weeks of exposure may not prevent the infection but can prevent it from becoming severe.

The JYNNEOS vaccine provides protection against monkeypox
The JYNNEOS vaccine is a two-dose vaccine developed to protect against monkeypox (also known as mpox) and smallpox. The vaccine is given as a subcutaneous injection of 0.5 ml, with two doses separated by a gap of four weeks or 28 days. The JYNNEOS vaccine is safer for usage in immunocompromised individuals as it does not cause the live virus to spread to other body parts or people. According to prior studies, the vaccine is about 85% effective. However, more research is needed to validate its current efficiency.
The JYNNEOS vaccine can be administered subcutaneously or intradermally. Subcutaneous administration involves injecting the vaccine into the fat layer underneath the skin on the back of the upper arm (triceps). Intradermal administration involves injecting the vaccine between the top layers of the skin on the forearm, upper back, or shoulder. Intradermal vaccination may result in less pain but more side effects such as itching, swelling, redness, thickening of the skin, and skin discolouration at the injection site.
It is important to note that the chickenpox vaccine does not provide immunity against monkeypox. Chickenpox is caused by the varicella-zoster virus and is not a member of the pox family of viruses. Therefore, having had chickenpox or the chickenpox vaccine does not protect against monkeypox.

Timing of the vaccine is critical for preventing monkeypox infection
The timing of the mpox vaccine is critical for preventing infection. The JYNNEOS vaccine, developed to protect against mpox and smallpox, provides the best protection when both recommended doses are administered. The second dose should be given 4 weeks after the first, and full vaccination is achieved two weeks after the second dose.
Getting the vaccine within four days of exposure to mpox can prevent the disease from developing. If the vaccine is received within two weeks of exposure, it may not prevent infection but can prevent the infection from becoming severe. This timing is critical for those at high risk of contracting the virus, which can spread through close contact and contaminated objects.
While the chickenpox vaccine does not provide immunity to mpox, the smallpox vaccine can offer protection. This is because smallpox and mpox are closely related viruses. Previous smallpox vaccination can provide some protection, but it may not be lifelong. During the 2003 mpox outbreak and the more recent outbreak, several people infected with mpox had been vaccinated against smallpox decades earlier.
The effectiveness of the vaccine also depends on an individual's immune system. As a result of the global eradication of smallpox in 1980 and the subsequent end of smallpox vaccination, nearly half of the current US population has no immunity to smallpox or mpox. This lack of immunity has contributed to the spread of mpox, with the virus affecting nearly 115 countries since its major outbreak in 2022.

Monkeypox is a viral illness caused by the monkeypox virus
Monkeypox, or Mpox, is a viral illness caused by the monkeypox virus, specifically a species of the genus Orthopoxvirus. It was first discovered in monkeys kept for research in Denmark in 1958, with the first human case reported in 1970 in the Democratic Republic of Congo. Since then, Mpox has been a recurring concern, with outbreaks in 2003 and 2022-2023, and a recent resurgence of cases in the Democratic Republic of Congo and other countries.
Mpox can be transmitted from animals to humans through bites or scratches, or through activities such as hunting, cooking, or playing with infected animal carcasses. It can also spread between people, primarily through close contact, and occasionally via contaminated objects or surfaces. The virus has affected nearly 115 countries and has been declared a Global Health Emergency by the World Health Organization (WHO).
To combat the spread of Mpox, vaccines are available and recommended for high-risk groups. The JYNNEOS vaccine, administered in two doses, provides protection against both Mpox and smallpox. The smallpox vaccine, due to the viruses' close relation, can also offer up to 80% protection against Mpox, though immunity may wane over time.
It is important to note that chickenpox, despite its name, is not a member of the pox family of viruses. Therefore, having had chickenpox or the chickenpox vaccine does not confer immunity to Mpox. However, individuals who have previously received a smallpox vaccine should still receive the Mpox vaccine following the same schedule as those unvaccinated against smallpox.
