How Effective Is The Covid
As with any vaccine, the Pfizer vaccine may not fully protect everyone who gets it. However, it is highly effective if people have both doses. That means, if you do catch COVID-19, youre far less likely to fall seriously ill and less likely to transmit the virus to others.
The COVID-19 vaccine stimulates your bodys immune system to produce antibodies and other proteins that will fight the virus if youre exposed to it. This reduces the risk of getting infected and if you do get COVID-19, it means you could have no symptoms or will have much fewer, milder symptoms and recover faster.
While the data is clear that vaccines protect people from the effects of COVID-19, research is ongoing to determine whether a vaccinated person could still transmit the virus to someone else so to be safe, we must assume there is still a risk of transmission.
Skipping The Second Dose
Why people are skipping their second dose, though, is up to pure speculation. Some incidents are likely due to scheduling mishaps or canceled appointments. But the rest might be for a variety of reasons: thinking one dose is fine, frustration after side effects from the first dose or even some fear of side effects from the second dose.
Should Pregnant Women Be Vaccinated
While pregnancy puts women at higher risk of severe COVID-19, very little data are available to assess vaccine safety in pregnancy.;
Pregnant women may receive the vaccine if the benefit of vaccinating a pregnant woman outweighs the potential vaccine risks.;
For this reason, pregnant women at high risk of exposure to SARS-CoV-2 or who have comorbidities which add to their risk of severe disease, may be vaccinated in consultation with their health care provider.

What Happens If I Dont Get The Second Shot At All
We dont know exactly what will happen if you dont get the second shot because that hasnt been studied yet.
From what we do know so far, its likely that one shot isnt as effective as two shots. This means that if you just get one shot, you could still get sick with COVID-19.;;
The Moderna and Pfizer vaccines were developed and studied using two shots, and we know that they are both extremely effective 94% and 95% at preventing COVID-19. Its possible that future studies will look to see how effective a single shot is. But for now its best to stick with what we know, which is that two shots work very well.

What Is A Chimpanzee Adenovirus
Adenovirus is a very common virus. Usually causing mild illnesses like the common cold, adenoviruses are widespread and efficient. There are more than 50 types of adenoviruses that cause respiratory infections, and they are good at moving into and attacking the body in various ways. A chimpanzee adenovirus is an adenovirus that causes these infections in chimpanzees.
When modified for use in vaccines, these viruses are very efficient at helping to produce immune responses. These types of vaccines, like the AstraZeneca vaccine, are known as viral vector vaccines.
The Municipal Commissioners Are Responsible For Monitoring The Vaccination Process
- FOLLOW US ON:
A dead person has received Covid-19 vaccine in Anantapur district of Andhra Pradesh, according to his family members. The son of the deceased man has received a message that his father has been vaccinated against Covid-19 at a vaccination center in the district. The man residing in the Hindupur city of Anantapur died in July. But his son received a message on his phone that his father had received both the doses of the Covid-19 vaccine.
The family members were embarrassed and angry over the incident. They alleged that the authorities involved in the vaccination process were not performing their duty carefully and registered dead persons for the vaccination on the Cowin platform.
The district administration is already facing severe criticism over the registration for Covid-19 vaccination. Currently, the vaccine is being taken by village and ward secretariats from the administration. This responsibility of vaccinating the beneficiaries has been handed over to the ANMs along with the medical staff. The Municipal Commissioners are responsible for monitoring the vaccination process.
The district-level authorities are saying that local staff members are sending messages to people who are yet to get the vaccine shot. The staff however said that it is occurring due to a technical glitch.

Why It Takes Two Weeks
If we’re patient, the FDA-authorized vaccines are all excellent at preventing disease .
“The efficacy of these vaccines is outstanding, but thats not realized until two weeks after the vaccination,” said Dr. Thomas Russo, the chief of infectious disease at the University of Buffalo’s Jacobs School of Medicine and Biomedical Sciences.
Why two weeks? “When you get vaccinated, your immune system gets a to-do list,” explained Mark Cameron, an immunologist at Case Western Reserve University who previously helped contain the outbreak of another deadly coronavirus, SARS, in 2003. What does the immune system need to do with the vaccine?
Our immune system will gradually recognize the spike protein as an intruder.
In response to recognizing this foreign spike protein, the bodies’ immune cells will cooperate to start producing protective proteins, called antibodies, to protect you against the virus. If you’re infected, these antibodies bind to the spike proteins of the virus, making it difficult or impossible for the virus to bind and gain access to our cells. .
“It’s around the two-week mark that the immune system is producing antibodies at levels that block infections,” said Cameron.
“Vaccinate and wait.”
“Vaccinate and wait,” he emphasized.
How Does The Two
At your first appointment, youll receive a vaccination card noting the manufacturer of the vaccine you receive, the dose and date. Keep the card youll need to present it to get the second shot and might need it in the future to prove youve been vaccinated. Tip: Take a photo of the card as a backup in case you lose it.
Your second dose should be the same manufacturer as your first shot, and in most cases you will receive it from the same vaccinator and likely in the same location. The process for scheduling your second-dose appointment differs depending on which vaccinator provides your shots.

When You Are Fully Vaccinated
People are considered fully vaccinated:
- 2 weeks after their second shot in a 2-dose series, like the Pfizer or Moderna vaccines, or
- 2 weeks after a single-shot vaccine, like Johnson & Johnsons Janssen COVID-19 Vaccine
COVID-19 vaccines are not interchangeable.;If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot.
You are;not;fully vaccinated if:
- it has been less than 2 weeks since your 1-dose shot
- it has been less than 2 weeks since your second shot of a 2-dose vaccine
- you still need to get your second dose of a 2-dose vaccine
How Long Does It Last
The symptoms of COVID arm typically last from 3 to 5 days. COVID arm wont escalate to a life threatening condition or serious allergic reaction. It is not associated with anaphylaxis.
Usually, the symptoms of COVID arm resolve on their own. However, if your symptoms are severe or if you feel very uncomfortable or worried, talk with a medical professional. They may be able to recommend medications, such as prednisone, that can help your symptoms resolve quickly.

Who Else Can Take The Vaccine
Vaccination is recommended for persons with comorbidities that have been identified as increasing the risk of severe COVID-19, including obesity, cardiovascular disease, respiratory disease and diabetes.;
Although further studies are required for persons living with HIV or auto-immune conditions or who are immunocompromised, people in this category who are part of a group recommended for vaccination may be vaccinated after receiving information and counselling.;
Vaccination can be offered to people who have had COVID-19 in the past. But individuals may wish to defer their own COVID-19 vaccination for up to six months from the time of SARS-CoV-2 infection, to allow others who may need the vaccine more urgently to go first.
Vaccination can be offered to breastfeeding women if they are part of a group prioritized for vaccination. WHO does not recommend discontinuation of breastfeeding after vaccination.;
Do I Need To Get Both Doses Of The Covid
Pfizer and Moderna are two-dose vaccines, so receiving both doses is crucial in ensuring maximum effectiveness. “People should not count on, ‘Okay, I had one, that’s good enough,'” Dr. Malvestutto explained. “Now that we have a vaccine, let’s make sure that we get the full protection that we can get from this.”
It is more challenging to get two doses, on both an individual and country-wide level, which is why we’re seeing that slowly-growing percentage of people skipping the second shot. Still, “we are going to do everything possible to make it as easy and as painless as possible for people to come back for that second shot,” Dr. Malvestutto emphasized. While one shot will provide some protection, getting both doses gives your body a significantly stronger defense. “If we know that it works best with two doses,” Dr. Malvestutto said, “then get the two doses.”

What Is A Third Dose Of The Coronavirus Vaccine
A third dose of the mRNA COVID-19 vaccines is identical to the first two doses. It can help protect people with weakened immune systems who did not have a strong enough response to the first two doses of one of the mRNA vaccines. Such people can get a third dose as soon as 28 days after a second dose. The FDA has authorized, and the CDC recommends, that those with certain medical conditions that suppress the immune system get a third dose of the same brand of COVID-19 vaccine that they initially received.

Scheduling Your Second Shot
- Planning for your second shot is important.
- If you need help scheduling your vaccination appointment for your second shot, contact the location that set up your first appointment.
- If you are having trouble or have questions about using a vaccination management or scheduling system, reach out to the organization that enrolled you in the system. This may be your state or local health department, employer, or vaccination provider.
- Scheduling an appointment for your second shot at the time you get your first shot is recommended, but not required.
- If you need to get your second shot in a location that is different from where you received your first shot , there are several ways you can find a vaccine provider for your second dose.
/6why Is Vaccination Important
We all have got vaccinated as kids for various infections and diseases. Vaccine is an important shield for protection against the novel coronavirus infection too. Though many people are scared of the side effects of vaccination, they need to understand that the protection offered by vaccination outweighs the temporary side effects it leads to in some people.

Vaccine Safety And Adverse Events Following Immunization
Due to limitations in the number of participants and duration of follow-up from COVID-19 clinical trials, medium- and long-term evidence on vaccine safety is limited. However, post-licensure vaccine pharmacovigilance is ongoing and safety signals around the world are detected and communicated globally. Clinical trials of the authorized COVID-19 vaccines excluded individuals with a history of severe adverse reaction associated with a vaccine and/or severe allergic reaction to any component of the vaccine. However, studies are ongoing.
The following section highlights key safety and AEFI data for the authorized and available COVID-19 vaccines. For additional details regarding trial design, including study population and length of follow-up, and safety for the COVID-19 vaccines authorized for use in Canada, refer to the evidence summaries in Appendix A , Appendix B , Appendix C , and Appendix D . Refer to Appendix E for a summary of the frequency of AEFI for the different COVID-19 vaccine products.
Refer to Part 2 – Vaccine Safety in the CIG for definitions of AEFIs and additional general information.
Very common and common adverse events
Common adverse events are defined as those that occur in 1% to less than 10% of vaccine recipients; very common adverse events occur in 10% or more of vaccine recipients. Please see Appendix E for a summary of adverse events identified in clinical trials of authorized, available COVID-19 vaccines.
Blood Products Human Immunoglobulin And Timing Of Immunization
NACI recommends that COVID-19 vaccines should not be given simultaneously with monoclonal antibodies or convalescent plasma.
To date, there is insufficient evidence on the receipt of both a COVID-19 vaccine and anti-SARS-CoV-2 monoclonal antibodies or convalescent plasma for treatment or prevention. Therefore, timing of administration and potential interference between these two products are currently unknown. Administration of these products close together may result in decreased effectiveness of a COVID-19 vaccine and/or anti-SARS-CoV-2 monoclonal antibodies because the monoclonal antibodies have high affinity for the spike protein expressed by the vaccines, which could prevent the production of antibodies stimulated by the vaccine.
In the post-exposure setting, expert clinical opinion should be sought on a case-by-case basis when deciding whether anti-SARS-CoV-2 monoclonal antibodies would be appropriate to administer after receipt of COVID-19 vaccine, taking into consideration the risk of exposure and the risk of severe COVID-19 disease in the individual.
To date, there is also insufficient evidence on the receipt of both a COVID-19 vaccine and any monoclonal antibodies or convalescent plasma for treatment or prevention of non-COVID-19 disease. Therefore, timing of administration and potential interference between these two products are currently unknown and expert clinical opinion should be sought on a case-by-case basis.

What You Need To Know
- If you receive a Pfizer-BioNTech or Moderna COVID-19 vaccine, you will need 2 shots to get the most protection.
- COVID-19 vaccines are not interchangeable. If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot.
- You should get your second shot even if you have side effects after the first shot, unless a vaccination provider or your doctor tells you not to get it.
- If you have a weakened immune system due to other diseases or medications, you can receive a COVID-19 vaccine if you have not had a severe or immediate allergic reaction to any of the ingredients;in the vaccine.
- People with moderately to severely compromised immune systems should receive an additional dose of mRNA COVID-19 vaccine after the initial 2 doses.
Why There Are Two Shots
Of the three COVID-19 vaccines available in the United States, two of them offered by Pfizer and Moderna require two doses while the Johnson & Johnson vaccine is a single dose. And the need for getting both doses of the two-shot vaccines, Dr. Goje says, comes down to the science.
Research during the trial phase for each of the two-dose vaccines showed that, after a certain time, the rate of immunity to COVID-19 plateaued with just one dose but that the second dose helped boost the immunity to higher rates.
According to studies cited by the CDC, data shows single-dose effectiveness of the Pfizer vaccine between 60% and 70%. A later study from the CDC showed 80% effectiveness with one dose of the Pfizer vaccine but 90% effectiveness with two doses. And Pfizer itself claimed 91% effectiveness after two doses with even higher rates of prevention against serious illness from COVID-19.
The numbers speak for themselves: Youre more protected with two doses than just one.

Some Coronavirus Variants Are A Concern
Johnson & Johnsons results also suggest that the B.1.351 variant appears to evade the protection offered by the companys vaccine.
Vaccine maker Novavax saw similar concerning signs. The company released preliminary results from its phase 3 trial on Thursday, Jan. 28, showing that its vaccine had an effectiveness of 90 percent in the United Kingdom, according to STAT News.
But the effectiveness dropped to 49 percent in South Africa, where B.1.351 is widely present.
The Centers for Disease Control and Prevention said Thursday, Jan. 28, that the
Dr. Anthony Fauci , the governments top infectious disease expert, said Friday, Jan. 29, during a COVID-19 press briefing at the White House that the lower efficacy of the Johnson & Johnson vaccine in South Africa is a wake-up call.
However, he added that vaccinating as many people as we can, as quickly as possible even if the vaccine has a lower efficacy can help keep new variants from emerging.
Viruses cannot mutate if they dont replicate, Fauci said. And thats the reason to continue to do what were doing.
The Johnson & Johnson results are from an interim analysis of its phase 3 clinical trial. The study included 43,783 volunteers 18 and older, with 468 symptomatic cases of COVID-19 occurring during the study.
The coronavirus vaccine developed by Oxford University and AstraZeneca uses a similar technology.
These interim results arent the end of the research for this vaccine.
