पशु चिकित्सक के पास टीका है।

पशु चिकित्सक is a compound noun:

• पशु = animal
• चिकित्सक = physician / medical practitioner

So together it means veterinarian or animal doctor.

This is a fairly formal word. In everyday speech, some speakers may also say things like जानवरों का डॉक्टर or even use वेट informally.

Hindi usually does not use a direct verb equivalent to English to have in sentences like this.

Instead, it uses this pattern:

X के पास Y है
= literally, Y is near/with X
= natural English: X has Y

So:

• पशु चिकित्सक के पास टीका है।
• literally: A vaccine is with the veterinarian.
• natural meaning: The veterinarian has a vaccine.

This is one of the most important possession patterns in Hindi.

Because के पास is a fixed postpositional expression meaning near / with / in the possession of.

With nouns, you normally use के पास regardless of whether the possessor is masculine or feminine:

• राम के पास
• सीता के पास
• लड़की के पास
• डॉक्टर के पास

So here, पशु चिकित्सक के पास is just the normal form.

With pronouns, the form changes in the usual pronoun way:

• मेरे पास = I have
• तुम्हारे पास = you have
• उसके पास = he/she has

Yes, technically it is in the oblique form, because Hindi nouns go into the oblique before postpositions.

However, चिकित्सक does not visibly change, because many consonant-ending nouns have the same direct and oblique singular form.

So:

• direct: चिकित्सक
• oblique singular: चिकित्सक

That is why you do not see a spelling change here.

Compare that with a noun like लड़का:

• direct: लड़का
• oblique: लड़के
• लड़के के पास

Here टीका means vaccine, vaccination, or shot, depending on context.

In this sentence, vaccine is the best interpretation.

Be aware that टीका can have other meanings in other contexts, such as:

• a mark on the forehead
• a commentary/explanatory note in formal/literary usage

But with a veterinarian and medical context, vaccine is the natural meaning.

Because टीका is singular.

In this possession structure, the thing possessed is what matters for singular vs. plural in the present tense:

• टीका है = there is a vaccine / has a vaccine
• टीके हैं = there are vaccines / has vaccines

So if you changed the sentence to plural, it would be:

पशु चिकित्सक के पास टीके हैं।
= The veterinarian has vaccines.

Hindi does not have mandatory articles like English a/an/the.

So टीका by itself can mean:

• a vaccine
• the vaccine

Context tells you which one is intended.

If you specifically want to emphasize one or make the indefiniteness clearer, you can add एक:

पशु चिकित्सक के पास एक टीका है।
= The veterinarian has a vaccine / one vaccine.

But in many situations, Hindi simply leaves एक out.

The sentence follows a very common Hindi order:

[possessor] + [possessed thing] + [है/हैं]

So here:

• पशु चिकित्सक के पास = with the veterinarian
• टीका = vaccine
• है = is

Hindi often puts the verb at the end, so having है last is completely normal.

Yes, Hindi word order is somewhat flexible, especially for emphasis.

For example, you may also hear:

टीका पशु चिकित्सक के पास है।

This still means the same thing, but it gives a little more focus to टीका.

That said, पशु चिकित्सक के पास टीका है is a very natural and straightforward order.

Yes. पास literally means near or close.

So के पास originally has a spatial meaning:

• मेरे पास आओ। = Come near me.

From that idea of nearness, Hindi also uses के पास for possession:

• मेरे पास किताब है। = I have a book.

So possession in Hindi is often expressed as something being with or near someone.

You add नहीं before है:

पशु चिकित्सक के पास टीका नहीं है।
= The veterinarian does not have a vaccine.

That same pattern works very widely:

• मेरे पास समय नहीं है। = I do not have time.
• उसके पास पैसे नहीं हैं। = He/She does not have money.

Yes, it is correct and natural, but it sounds somewhat formal or standard.

Depending on the speaker and situation, you might also hear:

• जानवरों का डॉक्टर = animal doctor
• वेट = vet

So पशु चिकित्सक is a good word to know, especially in written Hindi or careful speech.
