Anxiety is widespread among parents with young children.
Posts have been posted on SNS in recent days.
When I talked to a woman who posted on Twitter that the baby vaccination seems to be affected at the beginning, when the child caught a cold and went to her family's pediatrics, `` Notice of hib vaccination suspension '' It is said that I was surprised to find that it was pasted.
Vaccinations are not accepted
"We are preparing for the fourth vaccination in the spring, but prolonged suspension of shipments may affect us," he says.
From those who saw the post,
"I was told that I couldn't hit next because the stock was exhausted."
"It was said that the first or second vaccination would give priority to the still child."
The woman was saying, "I want proper information on how much is missing, how long the shortage will continue," she said.
Medical institutions around the world are also trying to respond to the vaccination schedule.
The “criminals” are the needles…
Why are vaccines in short supply?
The only manufacturer and seller of hibu vaccine in Japan is Sanofi, a pharmaceutical company headquartered in Shinjuku-ku, Tokyo.
According to the company, at the end of November last year, brown rust was found on a part of the surface of a syringe needle at a medical institution in Japan.
After that, rust was confirmed at another medical institution last December.
So far, two cases of rust have been confirmed nationwide.
Injection containers are from a different company ... the cause is unknown
The vaccine is a set of two types of containers.
One contains sodium chloride solution and has a stainless steel needle.
This is inserted into another container containing the powdered vaccine, prepared and administered to children.
So where did rust occur?
According to Sanofi, containers with needles are manufactured by another company.
After being delivered to Sanofi's factory in France, it is packaged with other parts and shipped to Japan.
"I'm sorry for the inconvenience and inconvenience of everyone, such as parents with small children and medical institutions," said a Sanofi representative.
Sanofi says, "We are investigating the cause of rust at various times, considering the various possibilities. It occurred during the manufacturing process, in a factory in France, after shipment to Japan, I don't know the details, but I understand that the needles are made of stainless steel and originally contain iron components and have oxidized for some reason. "
When to resume shipping
A hibu vaccine that supplies approximately 800,000 people in Japan annually.
If one person inoculates four times a year, the number would be 3.2 million.
Pharmaceutical companies have temporarily suspended shipments since January 28 to investigate the cause of rust.
What is the outlook for future supply?
Sanofi: "I would like to provide an outlook for the future supply around the end of February. We have assumed that the shipment will be temporarily stopped and have not received any information on health hazards so far. We will do our best to restart supply as soon as possible. ''
What is "Hib vaccine" in the first place?
"Hib" of hibu vaccine is "Hemophilus influenzae type b (Hib)".
It is similar in name to, but distinct from, the flu virus that spreads in winter.
When it enters the body through the mouth or nose and becomes infected, pneumonia,
▽ otitis media,
▽ "Bacteremia", where bacteria enter the blood and produce high fever,
▽ It causes swelling of the back of the throat, which can block the passage of air and make it impossible to breathe.
Bacterial meningitis, which causes inflammation of the membrane that surrounds the brain, can be a serious illness, and in some cases the ears and limbs are damaged or severely died.
Vaccination with vaccines is said to be highly effective in preventing infection.
In 2013, the law was amended, and it became possible to receive public funds, like polio and measles.
Many children from 4 months to 1 year and 6 months are infected.
を The target of vaccination is 2 months to under 5 years old,
▽ Maximum of four times.
Looking at the general schedule,
３ 3 times from 2 months to 5 months after birth,
And
７After 7 months to 13 months after the third vaccination, receive a fourth dose if you are over 1 year old.
However, it is said that the antibody can be produced even once when inoculated for the first time after one year old.
The first or second vaccination is given priority
In January, the Ministry of Health, Labor and Welfare informed a medical institution in January through a municipality nationwide that pharmaceutical companies would temporarily suspend vaccine shipments.
For the time being, we asked for the following measures until the supply stabilized.
し Make sure you buy the amount you need, and avoid unnecessary purchases.
▽ If vaccines are scarce and unavoidable, give priority to the first or second vaccination whenever possible.
In addition, when injecting the hibu vaccine, it is necessary to check the injection needle carefully and in the unlikely event that rust develops, avoid using it and immediately contact the pharmaceutical company.
Inoculation what should I do?
How do we deal with it?
We interviewed Mr. Masato Mine, director of "Mine Pediatrics" who is in charge of infectious diseases, etc., director of the Japanese Society of Pediatricians, who knows about vaccination.
Mine points out that "the vaccine is very effective and needs to be vaccinated."
In particular, it is important to receive the first and second inoculations within a fixed period, which means that about 80% of antibodies can be obtained.
For example, the effect of the vaccine continues for three months to half a year until the third vaccination, and the fourth dose is said to be ineffective for another one and a half years.
Mine: "In order to prevent infection, the first and second vaccinations should be checked at a local clinic and stocked positively. After the third vaccination, the vaccine effect will last for a certain period as described above. So you don't have to panic a month after the second time. "
In addition, he calls for this.
Mine: For the third and subsequent doses, it is desirable to receive a total of four doses when the vaccine is available. Even if the standard vaccination period has passed after contacting your medical institution, I want you to complete vaccinations that are too old. Check with your health care provider about the status of vaccine supply, and if you determine that the distribution has calmed down, make a plan and inoculate them. "
