تأخیر در تزریق دوز دوم واکسن گارداسیل مشکل ایجاد می‌کند؟

در دنیای پرهیاهوی امروز، گاهی برنامه‌ ریزی‌های ما دقیق پیش نمی‌رود. One of the concerns that occupy the minds of many people these days is "the exact date of the second dose of Gardasil vaccine". It may have happened to you that the date on your vaccine card has expired due to a cold, a sudden trip, busy work, or even the lack of Gardasil vaccine at the injection center.

The question that arises in the mind and shakes the body is: "Does the delay in injecting the second dose of the Gardasil vaccine cause problems?" آیا باید همه چیز را از اول شروع کنم؟»

در این مقاله، با تکیه بر پاسخ‌های تخصصی پزشکان و آخرین یافته‌های علمی، به شما می‌گوییم که چرا جای نگرانی نیست و چرا «تأخیر» به معنای «شکست» نیست.

آیا با تأخیر در دوز دوم گارداسیل، ایمنی ایجاد شده از بین می‌رود؟

پاسخ کوتاه و قاطع پزشکان: خیر. Gardasil vaccine contains virus-like particles (VLP) that strongly stimulate the immune system.

When you inject the first dose, Your body starts the process of making antibodies. According to the protocols of the World Health Organization (WHO) and the Center for Disease Control (CDC), if you are late in injecting the second or third dose, there is no need to repeat the course from the beginning.

The body's immune system has a long-term memory. Even if several months have passed since your injection, the body still remembers the previous exposure to the vaccine. As soon as you inject the next dose, your immune level will be back to where it should be.

distance Golden standard and interval for Gardasil injection

To know how much delay you have, you first need to know the standard intervals. Gardasil It is usually injected in 2 scenarios:

  • First dose: Zero time

  • Second dose: 6 to 12 months after the first dose

  • Note: If the second dose is injected earlier than 5 months, the third dose should be added.

b) 3-dose program (for people aged 15 to 45):

  • First dose: Zero time

  • Second dose: 2 months after the first dose

  • Third dose: 6 months after the first dose

Don't worry if you haven't injected in these intervals! Doctors believe that even if your second dose is injected 6 months later instead of 2 months, the body will still give the necessary immune response.

Many people become obsessed as soon as they realize that their 2 months are up and the Gardasil vaccine is not available in pharmacies. But you should know:

  1. High flexibility: Gardasil vaccine is one of the most flexible vaccines in terms of time. A delay of even one year does not make the doctor tell you to start the course from the beginning.

  2. Relative safety with the first dose: Research has shown that even a single dose of Gardasil provides a significant level of protection (although a full course is required for long-term stability). So you are not completely defenseless during this time.

delay in injection due to disease or drug interaction

One of the most frequently asked questions is: I have a cold, can I take Gardasil?

  • Mild illnesses: If you only have a runny nose or a mild sore throat without fever, Gardasil injection is safe.

  • Acute diseases: If you have a fever above 38 degrees or are undergoing severe infectious treatment, be sure to postpone the injection for 1-2 weeks. This intentional delay does not cause any problems for the vaccine to be effective.

Is it dangerous to delay the third dose of Gardasil?

The third dose actually guarantees 10 to 20 years of safety. If you don't get the third dose of Gardasil, your body still has a high level of immunity. Just complete it as soon as possible. There is no dead end in Gardasil injection.

difference 4-valent and 9-valent Gardasil in the delay time

It doesn't matter which type of Gardasil vaccine you get; The "no need to restart" protocol is true for both. Even if you took the first dose of 4-valence and now only 9-valence is available, according to the opinion of many experts, you can continue the course with the new type (under the doctor's opinion).

Errors Common: Restarting the HPV

vaccination course

Many non-specialized centers mistakenly tell clients that since 6 months have passed since the previous dose, you should start again from the first dose.

This work is not only financially burdensome, but also scientifically rejected. According to CDC guidelines: "Wherever the thread leaves off, pick up."

Many clients go to the doctor with fear and trembling and say: "I took the first dose 1 year ago and then forgot, is all the money and time I spent wasted?"

The scientific and decisive answer to these people is: There is no need to restart the course from the first dose. According to the World Health Protocol (WHO) and the medical recommendations mentioned, there is no such thing as "burning the previous dose" in the Gardasil vaccine.

Continuing the course after a long delay:

If more than a year has passed since your first dose, instead of worrying, follow this schedule:

  1. Inject the second dose as soon as possible: immediately into Center Get the Gardasil vaccine injection and get the second dose

  2. Regarding the interval for the third dose: At least 5 months (and preferably 6 months) after the injection of the second dose, proceed to receive the third dose.

  3. Continuity of Immune Memory: Your body has not forgotten the initial exposure to vaccine proteins last year. The second dose, which is injected now, plays the role of "strong recall" and raises the antibody level quickly.

Does delay in injecting Gardasil doses increase the risk of genital warts?

It is a false belief that “delay causes disease”. The delay itself won't introduce any viruses, but here's the trick: You're still not fully protected during the delay.

Many clients go to the doctor with fear and trembling and say: "I took the first dose a year ago and then forgot, is all the money and time I spent wasted?"

The scientific and decisive answer to these people is: There is no need to restart the course from the first dose. According to the World Health Protocol (WHO) and the recommendations also mentioned on the "Doctor Is" site, there is no such thing as "burning the previous dose" in the Gardasil vaccine.

Instructions Continuing the course after a long delay:

If more than a year has passed since your first dose, instead of worrying, follow this schedule:

  1. Inject the second dose as soon as possible: Go to the vaccination center immediately and receive the second dose.

  2. Regarding the interval for the third dose: At least 5 months (and preferably 6 months) after the injection of the second dose, proceed to receive the third dose.

  3. Continuity of Immune Memory: Your body has not forgotten the initial exposure to vaccine proteins last year. The second dose, which is now injected, acts as a "strong booster" and raises the antibody level quickly.

Necessary after injecting the second dose (especially for delayed cases)

Many users report that they may experience more local reactions after a delayed second dose than the first dose. This is completely normal and indicates that your immune system "remembered" immediately after receiving the vaccine and started to work hard.

  • Pain and swelling at the injection site: It is recommended to use a cold compress in the first 24 hours.

  • Mild fever or fatigue: These symptoms indicate the activation of the immune response and usually resolve within 48 hours.

  • Doctor's advice: In case of severe allergy, be sure to consult your doctor.

When you decide to make up your overdue doses, the question comes to you, Where should we go to inject the Gardasil vaccine? It is very important to choose a reputable center that, in addition to providing the original vaccine, will provide you with expert advice on time intervals. One of the centers that Tehran offers specialized services in this field is the office of Dr. Mojdeh Namdari.
