We offer COVID-19 vaccinations 24/7 to all age groups. These vaccinations stimulate the production of antibodies in the body against SARS-CoV-2 virus, the causative agent for COVID-19. These vaccinations remain effective for a certain period of time. The vaccination can only be more effective if the community practices safety measures at-large as the virus can mutate too. If the virus’s genome undergoes mutation, a new vaccination will be required for the changed virus.
COVID-19 Pfizer Vaccine Registration for Adolescents 12-17 Years
Please fill-in the online form below to get an appointment for the COVID-19 vaccination. Only Pfizer and Moderna are available for free to everyone above 12 years of age in the USA, regardless of insurance or immigration status.
Who should get the Pfizer COVID-19 vaccination?
The Pfizer-BioNTech vaccination is for people above 12 years of age.
Who Should Not Get Vaccinated
- People who have experienced a mild or severe allergic reaction (anaphylaxis) to any component in the mRNA COVID-19 vaccine, such as the polyethylene glycol, must not get an mRNA COVID-19 vaccine.
- If you have suffered from an allergic reaction after receiving your first mRNA COVID-19 vaccine dose, you should not get the next dose of any of the mRNA COVID-19 vaccines.
- An instant allergic reaction occurs within 4 hours of exposure, and has swelling, wheezing, or hives symptoms. These are the signs of respiratory distress.
- A severe allergic reaction is when the patient needs to get medical care, EpiPen or epinephrine treatment.
COVID-19 Vaccination – Side-Effects
The risk of side-effects is very low in COVID-19 vaccinations. Still, you may experience redness, pain, and swelling at the site of inoculation. Other possible side-effects are headache, tiredness, muscle pain, fever, chills, and nausea.
The side-effects of vaccination do not manifest immediately but happen in 1 to 2 days after the vaccination shot. These signs indicate the healthy development of protection mechanisms in the body against COVID-19 germs and go away in a few days.

Other COVID-19 Vaccinations – Johnson & Johnson and Moderna Vaccinations
The single-dose Johnson & Johnson and 2-dose Moderna vaccination is for adults over 18 years. You don’t need a registration or appointment from us to get these vaccinations. People who want this vaccination can walk-in anytime from Monday – Saturday between 9 am and 5 pm.
Third Vaccine Dose (Booster Dose)
The 3rd dose of vaccine is only for people with weak immune systems who have either received a Moderna COVID-19 vaccine or Pfizer-BioNTech vaccine. It is also a booster dose.
Vaccine Boosters
Vaccine booster shots are given after the completion of the COVID-19 vaccination dosage when the immunity developed in the person gets weak with the passage of time. Pfizer-BioNTech COVID-19 vaccination booster is only offered to specific people, according to the recommendations of the CDC.
Pfizer BioNTech booster shots can only be applied to people who completed their vaccination at least 6 months before.

The immunity developed by the COVID-19 vaccinations decreases with time. The vaccine booster increases the immunity and is administered only after the completion of the initial vaccination dosage to get more antibodies.
The findings of a small clinical trial proved the effectiveness of the Pfizer-BioNTech booster shot in strengthening the immune response in the test’s participants. The participants had completed their primary vaccination series 6 months before, and the Pfizer-BioNTech booster shot enhanced their immunity significantly. The booster shots are also effective against the delta variant.
COVID-19 vaccination and booster shots are effective against the Delta variant of coronavirus. However, the protection offered by the COVID-19 vaccinations decreases with time, and the extent of protection varies among individuals. The delta variant is more infectious than other variations of the SARS-CoV-2 virus. These aspects of COVID-19 vaccination are under exploration.
Presently, the COVID-19 booster shots are prioritized for people above 65 years of age. The risk of a severe COVID-19 infection increases with age, with older adults being most susceptible. Moreover, the risk is higher in patients with underlying medical conditions. Booster shots are only available for some Pfizer-BioNTech Vaccine recipients. Only certain populations initially vaccinated with the Pfizer-BioNTech vaccine can get a booster shot at this time. Older adults and 50-64 year old people with medical conditions
People aged 65 years and older and adults 50–64 years with underlying medical conditions should get a booster shot of Pfizer-BioNTech vaccine. The risk of severe illness from COVID-19 increases with age, and can also increase for adults of any age with underlying medical conditions.

A vaccine consists of weakened or dead molecules of virus, known as antigens. These antigens trigger a defense mechanism in the body causing the immune system to synthesize antibodies against the virus to neutralize it. Antibodies formed against every microorganism are different from one another and they bind with the virus to neutralize it.
There are 4 main categories of vaccines: (looks more technical.. suggests not to add)
- Live vaccines: Live vaccines make use of weak form of virus to synthesize the antibodies
- Inactivated vaccines use dead virus
- Toxoid vaccines use toxins synthesized by the virus to establish immunity against the segment of the virus which causes disease
- Polysaccharide, recombinant, conjugate, and subunit vaccines use proteins and other fragments of virus
- Vaccines are also synthesized by using the genetic material of the virus, DNA or RNA

COVID-19 vaccinations are available free of cost.
Yes, the Food and Drug Administration Authority (FDA) evaluated, reviewed and approved a few COVID-19 vaccines for effectiveness, safety, and quality.
All COVID-19 vaccinations have been developed through a multi-stage and rigorous testing process comprising many trials involving tens of thousands of individuals.
The COVID-19 vaccination is inoculated in the muscle of the upper arm. Certain COVID-19 vaccinations comprise just 1 dose, while others comprise 2 doses, with 3-4 weeks gap.
Yes, it takes time for the immune system in your body to develop immunity against COVID-19 by synthesizing antibodies.
No, vaccinations are developed against bacterial infections, and many other types of virus-caused infection such as Influenza, Chicken pox, Hepatitis, and MMR.
Yes, data suggests the WHO approved vaccines Pfizer/Bion Tech, Moderna, Johnson and Johnson, AstraZeneca/Oxford, Sinovac, and Sinopharm to be safe for HIV patients.
The minimum age to get the Astrazeneca vaccine is 18 years. However, this fact needs to be validated by further studies in-progress.
