In Argentina, there are already 22 confirmed cases and 96 suspected cases reported, according to data from the Ministry of Health.
Moderna is developing an experimental vaccine against the monkeypox (mpox)powered by the Messenger RNA (mRNA). The substance demonstrated a Greater efficacy in reducing symptoms and disease duration than other options currently available, according to an animal test published Wednesday by the scientific journal Cell.

Monkeypox is declared at its highest alert level by the World Health Organization (WHO)and this new discovery comes in the midst of a outbreak of the disease in Africapartly driven by a new variant that emerged in the Democratic Republic of the Congo and was declared an international emergency.


The vaccine includes genetic instructions that train the host’s immune system to recognize four key viral antigens, which enable the virus to attach to cells. Co-author of the study, Jay Hoopera virologist at the U.S. Army Medical Research Institute of Infectious Diseases, said researchers were looking to explore mRNA technology to ensure both safety and efficacy. This is the same technology used in its coronavirus vaccine.
The tests were carried out on 18 primates. The first six were vaccinated with the mRNA-based dosewhile six others received the currently authorized vaccine (JYNNEOS). The rest did not receive no doseEight weeks later, the animals were exposed to a lethal strain of mpox.
At the end of the cycle, The six who were not vaccinated died, the group vaccinated with JYNNEOS had a maximum of 607 lesions and the one that had the mRNA dose had only a maximum of 54 lesions. In addition, the new vaccine shortened by more than 10 days the period during which the animals presented conditions with respect to the currently available vaccine; as well as reduced the viral load in the blood and throatsuggesting it would be effective in reducing transmission.
Alec Freynlead inventor of the Moderna vaccine, said the serum was also tested against other viruses in the Orthopox family, and effectively neutralized vaccinia virus, cowpox, rabbitpox, camelpox and ectromelia. The vaccine candidate, dubbed ARNm-1769, is now in early-stage human trials in the United Kingdom to assess its safety and immune response.
What should I do if I have monkeypox?
Mpox, or monkeypox, is a disease caused by the monkeypox virus, which belongs to the genus Orthopoxvirus.This viral disease is distinguished because among its main symptoms is the appearance of skin rashes that appear as pimples or blisterswhich They are usually located on the genitals, perianal area, face, hands or feet.
If a person is diagnosed with mpox It is important that you remain calm and Follow these tips:
- You should follow the recommendations of health personnel.
- It should be kept isolated until all the scabs have fallen off.
- It is important not to touch the lesions to avoid infections.
- You should not touch your eyes, as this could cause injury by transferring the virus from your hands.
- You must wear a mask at all times when you are around other people.
- You should wash your hands with soap and water for at least 20 seconds or disinfect them with 70% alcohol gel, and keep your fingernails trimmed.
- It is essential that you do not share dishes, cutlery, clothing, sheets, bath towels, toiletries (such as toothbrushes, razors, etc.) or sex toys with other people.
- You should identify people with whom you had close contact (more than one hour without a mask and physical contact) up to three weeks before contracting monkeypox and mention them to health personnel.
- When sweeping, care must be taken not to spread dry contaminated material from the lesions.
- You should frequently disinfect surfaces and objects in shared areas with 70% alcohol or a bleach solution.
- It is crucial to avoid physical contact (such as hugging, kissing, or sexual intercourse) until you are fully recovered.
- You should keep your pet away from you to avoid the risk of transmitting the virus to them.
- You should avoid contact with people with chronic illnesses, pregnant women, young children and the elderly, as they are more vulnerable to complications.
What to do if there is a person with mpox at home?
If someone you live with tests positive for mpoxone has to follow these tips at home:
- The person should be kept isolated in a room, preferably with its own bathroom.
- Both the patient and the person caring for them must wear a mask during care and when handling their clothing or bedding.
- It is recommended to wear a mask and disposable gloves when entering the room.
- Dirty clothes and bed linens of the sick person should be handled with gloves, avoiding shaking them and placing them quickly in a bag, without mixing them with the rest of the clothes. They should be washed with hot water, plenty of detergent and, if possible, bleach. It is important to wear gloves when washing clothes.
- The infected person’s cutlery and dishes should be washed with hot water and detergent.
- All surfaces in the bedroom and bathroom should be cleaned and disinfected with bleach water or alcohol.
