Not sure about your PPV, but my friend who went to 2nd dose at PPV Bkt Jalil had a separate queue from 1st dose.

In addition to PICK walk-in, there are also Selvax walk-in and also other ad-hoc PPV discussed here.

A lot of choices.

Yes....

As per the explanation given by PPV Vision, the Pfizer needs dilution.

I think that's why people getting Pfizer is already pre-filled in the syringe and not straight from the vial.

Same batch as PPV Vision walk-in event on Aug 1st.

Don't wait, just go walk-in vaccination at the selected PPV.
Either walk-in or by mySejahtera, you will still need to go to a PPV anyway.

The good thing about walk-in is, you have the control on which PPV to go.

Once you have an appointment, you cannot choose other PPV anymore (if it happens to be a crowded PPV)

I'm not sure if there is anything to worry about.

There are many factors involved, such as the room lighting, the angle you look at the syringe, the angle the nurse holding the syringe, the background wall color when you were looking at it, the NaCl solution when vaccine is mixed with, and many other factors.

If there any concrete data available what you had is not a vaccine? The fear needs to be substantiated.

What are you doing to do with that suspicious fear? Go for a serology test? an Antibody test?

All PPV at Klang Valley is now closed, you will need to contact your nearest gov Klinik Kesihatan
