The article in the Hindu is from August 11.. Most of recent news article I see is Zydus DNA vaccines ZyCoV- D only.
FWIW: There are about 7 Vaccines approved/EUA in India - About 13 Clinical Trials .
Approved:
- Zydus Cadila (ZyCoV-D) DNA
- Moderna (mRNA-1273) - mRNA
(Non Replicating Viral Vector)
- Gamaleya ( Sputnik V) - :
- Janssen (Johnson & Johnson) (Ad26.COV2.S)
- Covidshield (Serum India AZ formula)
-Oxford/AstraZeneca (AZD1222) - Same formula as above.
- Inactivated Virus -
Bharat Biotech's Covaxin.

The following ones are on clinical trials but not approved in India yet (to best of my knowledge)
Novovax, and Covavax (same formula) (Covavax has been approved in at-least 2 countries)
Biological E Limited (BECOV2A, 2B, 2C, 2D - all protein subunit also).
We also have mRNA type vaccine on clinical trials - (Gennova Biopharmaceutical's HGCO19)
BB also has viral vector vaccine (BBV154 - Covaxin has been quite successful - this is their other vaccine).
There are a few more but above ones are quite well known.
(For perspective there are *many* trials and vaccine candidates on various stages in India (and other countries)
