At previous posts, we talked about possible vaccines for Covid-19 (please read: Updates of Vaccines to Combat Covid-19 – Virus 12 and When Will Vaccine for Covid-19 Available? - Virus 4).

The good news that we are in phase 3 clinical trials with 30,000 volunteer at 89 different site in the USA now.

We might have questions:
- is safe for human?
- what is safe dosage of Covid-19 vaccines?

Yes, vaccine, in this case, developed by cooperation between federal agency and biotechnology company, National Institutes of Health's National Institute of Allergy and Infectious Diseases (NIH) and Moderna is safe.

It is reported safe because it had been went through two clinical phases, and will complete final phases with thousand volunteer soon.

There are 3 dosages are tested so far:
- 25 micro gram (µg)
- 100 µg
- 250 µg

The results shown that all 3 dosages have positive impacted where its generated immune responses. No serious effects have been recorded.

The phase 3 will involve dose of 100 µg, it is medium doses. Researchers use this medium dose, because:
- at first shot, there is little reaction.
- after 1 month, there is moderate reaction at second shot.

In case of 25 µg dosage, the reaction is mild. There is severe reaction when using 250 µg dosage.

We are waiting the best outcome from clinical trials of 300,000 volunteer as soon as possible, probably by next 3 months!

Homemade face masks

We have at least three farmer markets close by our neighborhood, they mainly selling produces from vegetable to fruit, flowers to potatoes, honey to cheese and any farming relate produces.

The markets open hours from 6.30 AM to 6.30 PM, and 7 days a week. Not quite short hours compared to ethnic groceries which open from 9.00 AM to 7.00 PM only.

However, one of our neighborhood “farmer market” is different than others in term of selling items and opening hours, the market called as “Harb Oasis.”

This market is collection of small vendors (farmers), they rented the available spaces. Market management said that there are 50 stalls.

It is open about 5 hours, from 8.30 AM to 1.30 PM. But, some booths may little bit longer, maximum at 3.00 PM, depend very much on the number of visitors. If there is crowd, then longer opening hours will be.


Bracelets, homemade accessories

The Harb Oasis is a weekly “farmer market,” every Saturday. 50 vendors fall in categories of:

- farmers
- food sellers
- craft makers
- artists 



Summer style and accessories

We may find plenty of products to buy. Selling items include:
- handcrafts
- art works
- jewelry
- toys
- soaps
- fashion accessories


Art works from community


In addition to shopping, visitors may enjoy live music. We may tastes many different kind of foods sold by food trucks at the corner of market.

Is there weekly farmer market or any weekly market in your area? How long its opening hours?
