Who is eligible to get the vaccine?

As of May 13 2021, all 12 yo and older are able to get the Pfizer Covid vaccine after months of rollout in profession-based then age-based phases.

Pfizer vs Moderna vs JNJ, which one is better?

The CDC recommends us to get whichever vaccine we can as soon as possible. All trhee vaccines have been carefully and rigorously reviewed and approved by the FDA under Emergency Use Authorization.

What is the vaccine’s effectiveness?

Based on clinical studies released, the vaccine is 95% effective after series of 2 doses of either Pfizer or Moderna, while the single dose JNJ is 66%.

What are the side effects for the Covid-19 vaccine?

Most common are sore arm at injection site, headache, tiredness, chills and fever. Most are temporary, transient, and can be managed and gone within a day or two.

In some very rare cases, some patients do experience severe allergic reactions and required to be treated with Epinephrine or go to the hospital. This happens with every single medication and vaccine out there, whether it is new or old, developed fast or slow. Please alert your healthcare provider if you have experienced any severe allergic reaction any medication or vaccine prior to Covid-19 vaccination.

What are the long term side effects of the vaccine, like in 5 or 10 year? I am worried because it is too new and developed too fast.

The vaccines are new and the CDC and FDA are still compiling all data as we speak. However all the experts have agreed that the benefits far outweigh the side effects at this point. As of May 2021, there have been 580,000 deaths due to Covid in the US, thus it is critical that all eligible persons get the vaccine as soon as possible.

How much will it cost?

The Vaccine is provided by the Federal Government, at no cost. The administration fee might be applied, and billable to appropriate insurance plan etc.

We are obligated to bill your insurance for administration fees first, thus we do request you to disclose your insurance information as needed. Rest assured, we keep all information confidential and we do not turn anyone away based on immigration status, insurance coverage and any other factors. Our primary job is to get each and every one of you vaccinated timely.

Is there a shortage of vaccine?  What if I cannot get my second dose?

We are in the middle of a worldwide pandemic situation, thus resources are limited and must be allocated carefully. Get your first dose as soon as your group is included in the CDC released phase.

There are several Covid-19 vaccine under development by other drug manufacturers, and they are expected to be reviewed and possibly approved by the FDA in the near future. Thus supply and availability of Covid-19 vaccine will be increased soon.

As of May 2021, the supply has met all the demands in the US, and we are closing to herd immunity.

Is it safe in pregnancy? Breastfeeding?

The CDC recommends those patients to discuss it with their healthcare providers about the pros and cons of getting vaccinated. No data is available yet, but if you are in a high risk of getting infected by Covid-19, then the pros will outweigh the cons. Same recommendation for breastfeeding.

If you decide to receive Covid-19 vaccine, you are encouraged to enroll in v-safe to report potential side-effects so that we will have more data going forward.

I won’t get the vaccine because it was developed by using fetal cells.

The Vatican has clarified its position regarding Covid-19, and recommends its followers to get vaccinated.

Do I need to wear a mask, social distance once I have my first dose? How about after the second dose?

The short answer is YES, YES and YES.

  1. Our body needs time to build immunity and produces antibodies to protect against future infections by the same virus. It is usually 10 to 14 days after you get vaccinated.
  2. First dose: current data show 50 to 70% of patients get immunity after the first dose. Thus, many will still be vulnerable to serious Covid-19 infection.
  3. Second dose: yes, data show that 94% effectiveness about the Covid-19 vaccine. However, there is still a 5% chance that you do not develop antibodies or immunity against Covid-19. Even if you have immunity, it does not mean that you will not get infected. Having immunity or antibodies against a particular bacterium or virus just means that your body is ready to fight that infection, thus give you a better chance of overcoming the infection really fast and not get seriously sick if infected. However, those around you without antibodies/immunity can still get infected by you and get seriously sick. So please wear your mask, social distance etc to protect yourself and those around you.
As of May 15 2021, the CDC has released new guidance to allow those who are fully vaccinated to go without mask with some restrictions. However, State and local Health Department have the final say on their own policy regarding mask requirement. More information to come soon for Orange and LA counties.
